Sprains and strains: Causes, signs, prevention, types, treatment

Have you ever twisted your ankle during a morning run or felt a sharp pain in your back after lifting heavy objects? 

Sprains and strains are common injuries that can disrupt our daily lives, affecting anyone from professional athletes to occasional gym-goers. 

Surprisingly, many physical injuries in emergency departments are related to these conditions. 

This guide aims to provide you with essential knowledge on the causes, symptoms, and treatments for sprains and strains, helping you prevent future injuries and manage them effectively.

What is the difference between a sprain and a strain?

Though these terms are often used interchangeably, they refer to injuries of different tissues in the body.

A sprain occurs when you stretch or tear the ligaments, the tough bands of fibrous tissue that connect two bones in your joints. Common areas affected include the ankles, knees, and wrists [1]. 

The severity of a sprain can range from a mild stretch with intact ligaments to a complete tear. This type of injury often happens when a joint is forced beyond its normal range of motion, like twisting an ankle.

While sprains involve ligaments, strains affect muscles and tendons, the tissues that connect muscles to bones. This distinction is key in understanding these injuries. 

Strains often result from overstretching or tearing a muscle or tendon, typically occurring in the back, hamstring, or other muscles used in active movement [2]. 

Symptoms can include pain, muscle spasms, weakness, and reduced mobility in the affected area.

Strains are injuries to muscle fibers or tendons, which anchor muscles to bones. They can result from a single event, such as incorrectly lifting a heavy object or repetitive movements that place stress on the muscle or tendon. 

Depending on the severity, strains can be a superficial overstretched muscle or a more severe injury involving partial or complete muscle fibers or tendon tears.

The primary confusion between sprains and strains lies in their similar symptoms, including pain, swelling, and limited flexibility or range of motion. 

However, remembering the key difference — sprains involve ligaments and joints, while strains involve muscles or tendons — helps identify the injury correctly. 

This understanding is essential for seeking appropriate treatment and supports a quicker, more effective recovery process. 

Recognizing the nature of the injury helps in applying the correct immediate care and following the most effective rehabilitation plan.

What causes sprains and strains?

Identifying the root causes of sprains and strains can significantly aid in prevention. Despite their differences, both types of injuries share common triggers but also have their distinct causes.

How are sprains caused?

Sprains are often the result of sudden, unexpected movements. These include turning your ankle when walking on uneven ground, falling in a way that bends your wrist back, or a sudden pivot during sports activities. 

Activities that involve quick changes of direction, like basketball, soccer, and tennis, are particularly high-risk. 

Even daily activities, when done carelessly, can lead to a sprain if the body moves awkwardly or without proper support.

What are the causes of strain?

Strains, on the other hand, are frequently caused by overexertion or improper use of a muscle. 

This can happen in various scenarios, from lifting heavy objects with poor form to engaging in repetitive motions without adequate rest. 

Sports that require a high degree of sprinting, jumping, or explosive starts, like track and field, can increase the risk of muscle strains. 

Occupational and everyday tasks involving heavy lifting or repetitive motion can also be culprits.

What factors increase your risk of acquiring sprains or strains?

What factors increase your risk of acquiring sprains or strains?

Certain factors can elevate your risk of experiencing either sprains or strains. These include:

1. Previous injuries 

A history of sprains or strains makes it more likely to injure that part again.

2. Physical condition

Poor conditioning can increase the risk as muscles and ligaments are not adequately prepared for certain activities.

3. Fatigue

Tired muscles are less likely to provide good support for your joints, leading to a higher risk of injury.

4. Improper equipment

Wearing footwear that doesn’t provide adequate support or using equipment that’s not right for your activity or body size can increase your risk.

5. Age and flexibility

Your ligaments become less flexible as you age, making them more prone to injuries. Similarly, a lack of flexibility or muscle strength can lead to strains.

What are the signs and symptoms of sprains and strains?

While they share some common signs, understanding the specific indicators and severity levels can guide your next steps, including when to seek medical attention.

What are the symptoms of a sprain?

Sprains manifest through a variety of symptoms, primarily around the affected joint. Key signs include [3]:

  • Pain that worsens when moving the joint
  • Swelling and bruising
  • Limited flexibility and range of motion
  • A popping or tearing sensation at the time of injury

Sprains are classified into three severity levels:

  • Grade 1 (mild) – Slight stretching and microscopic ligament tears.
  • Grade 2 (moderate) – Partial tearing of the ligament, marked by abnormal looseness in the joint when moved in certain ways.
  • Grade 3 (severe) – Complete tear of the ligament, leading to significant instability and immobility of the joint [4].

What are the signs of a strain?

Strains, affecting muscles and tendons, exhibit different symptoms, such as [2]:

  • Pain or tenderness
  • Muscle spasms
  • Weakness
  • Swelling
  • Limited ability to move the affected muscle

Similar to sprains, strains are also categorized by severity:

  • Mild (grade 1) – Slight muscle fibers, tendon stretching, or minor tears.
  • Moderate (grade 2) – More extensive muscle or tendon damage, with impaired muscle function.
  • Severe (grade 3) – Complete muscle or tendon rupture, requiring immediate medical intervention [5].

When should you seek medical attention for a sprain or strain?

While many sprains and strains can be treated at home with the RICE method, certain situations require professional medical care. Seek immediate medical attention if you experience:

  • Severe pain and swelling
  • Inability to put weight on the affected area
  • Signs of infection, like redness, warmth, or fever
  • Numbness in the injured area
  • No improvement after a few days of self-care

Understanding these signs and acting promptly can prevent further injury and ensure a quicker return to daily activities or sports. 

Always err on the side of caution and speak with your healthcare provider if you’re unsure about the severity of your injury.

What are the most common types of sprains and strains?

Sprains and strains can occur in various parts of the body, each presenting its own set of challenges and requiring specific treatment approaches. 

Understanding the common types helps one recognize how the severity and treatment options may vary depending on the injury’s location.

Common sprains

Ankle sprains

One common injury, particularly among athletes, is an ankle sprain caused by the foot turning inward and stretching or tearing the ligaments on the outside of the ankle.

Wrist sprains

Due to falling on an outstretched hand, wrist sprains can range from mild to severe, impacting one’s ability to carry and hold items.

Knee sprains

These involve the ligaments that hold the knee joint together and can be particularly debilitating, affecting mobility and stability.

Common strains

Hamstring strains

Located at the back of the thigh, these are common in athletes who engage in sports requiring quick starts, like track and field. Recovery can be prolonged, especially for severe tears.

Back strains

Back strains can result from lifting heavy objects incorrectly or sudden movements, causing significant discomfort and limiting daily activities.

How do you treat each type?

The treatment approach and recovery time for sprains and strains depend significantly on the injury’s location and severity. 

For instance, mild ankle and wrist sprains may be managed with home remedies, such as rest, ice, compression, elevation, and over-the-counter pain medication. 

In contrast, severe knee sprains might require immobilization with a brace or even surgery to repair torn ligaments, followed by physical therapy to regain strength and mobility.

Similarly, hamstring strains may necessitate a more extended rest period, especially for athletes, to prevent re-injury. 

Back strains might require a combination of rest, physical therapy, and, in some cases, stronger pain relief measures to manage symptoms and facilitate recovery.

The key to effective treatment lies in accurately diagnosing the severity of the injury and tailoring the recovery plan to suit the specific needs of the affected area. 

Early intervention and adherence to a prescribed rehabilitation program significantly impact the healing process, helping to restore function and prevent future injuries.

What is the proper treatment for strains and sprains?

Knowing how to respond can significantly impact your recovery trajectory when dealing with sprains and strains.

Treatment options vary depending on the severity of the injury, but starting with first aid can ease symptoms and prevent further harm.

First aid: The RICE method

The RICE method is a widely recommended first response to acute injuries and stands for [6]:

  • Rest – Limit activities to avoid putting weight on the injured area.
  • Ice – Apply ice wrapped in a cloth to reduce swelling and pain. Use for 20 minutes every two to three hours during the first few days.
  • Compression – Use an elastic bandage around the injured area to minimize swelling, but not so tight as to cut off circulation.
  • Elevation – Keep the injured area raised above heart level to reduce swelling.

Advanced medical treatments

For injuries not improving with basic care, or for more severe cases, professional medical treatment may be necessary:


OTC pain relievers like ibuprofen or acetaminophen can help manage pain and reduce inflammation. In some cases, stronger prescription medications may be needed.

Physical therapy

A tailored program can restore strength and flexibility to the injured area, which is crucial for both recovery and prevention of future injuries.


Though rare, severe cases, especially complete tears, might require surgical intervention to repair damaged ligaments, muscles, or tendons.

Home remedies and care strategies

In addition to RICE, gentle stretching and strengthening exercises, as your healthcare provider recommends, can aid in recovery. Maintain a healthy, balanced diet to support tissue repair.


Rehabilitation is a cornerstone of the recovery process. It not only aids in healing but also strengthens the injured area to prevent re-injury. 

A well-designed rehab program, possibly including exercises to improve balance, strength, and flexibility, is essential for a full return to pre-injury activity levels.

Understanding and applying these treatment methods can help ensure a swift and effective recovery from sprains and strains. 

Emphasizing rehabilitation is especially important, as it plays a pivotal role in safely resuming activities and guarding against future injuries.

How long do sprains and strains take to heal?

The journey to recovery after a sprain or strain varies significantly depending on the severity of the injury and the individual’s overall health.

What supplements can help with sprains and strains?

When recovering from sprains and strains, certain supplements may support the healing process, though it’s crucial to consult a healthcare provider before starting any new supplement regimen [7].

  • Vitamin C is known for its role in collagen synthesis, an essential component of ligaments and tendons, potentially aiding in the repair of these tissues.
  • Omega-3 fatty acids, found in fish oil supplements, help reduce inflammation, which is beneficial during the initial recovery phase of sprains and strains.
  • Vitamin D and calcium are essential for bone health, particularly if the sprain or strain is near a joint, supporting the overall recovery of the musculoskeletal system.
  • Magnesium helps with muscle function and can reduce spasms, a common symptom of strains.
  • Zinc is important in wound healing and tissue repair, potentially accelerating recovery from these injuries.

Do’s and don’ts when you have a sprain or a strain

Managing a sprain or strain effectively requires carefully balancing activities and precautions. Here are some do’s and don’ts to help guide your recovery and ensure that you’re on the fastest path to returning to your normal routine.


  1. Follow the RICE protocol. Rest, Ice, Compression, and Elevation are your first lines of defense against swelling and pain. Apply these measures immediately after the injury and in the days following to minimize symptoms.
  2. Use pain relief wisely. Over-the-counter pain medications can reduce discomfort and inflammation. Use them as directed and consult a healthcare provider for the best options.
  3. Stay active within reason. Light activities and exercises that don’t stress the injured area can maintain your overall fitness and facilitate recovery. Consult a physical therapist for appropriate exercises.
  4. Listen to your body. Heed the signals your body sends. If an activity causes pain, stop and rest. Pushing through pain could lead to further injuries.
  5. Seek professional advice. If your symptoms persist or worsen, see a healthcare provider to ensure you’re on the right track and prevent complications.
