The most common cause is when the muscle group is stretched beyond its normal range.
This problem is more common in people who play sports, such as running, jumping, soccer, basketball, or football. Other things that may raise your risk are:
- Tight quadriceps
- A muscle imbalance
- Weak muscles
- Muscle fatigue
Problems may be:
- Pain in the front of the thigh
- Bruising and swelling
- Muscle stiffness
- Muscle weakness
You will be asked about your symptoms and health history. You will be asked how the injury happened. A physical exam will be done. It will focus on your thigh. This is often enough to make the diagnosis.
Most strains heal in about 3 weeks. It can take up to 6 months for a severe strain to heal. The goals of treatment are to ease pain and swelling. This may include:
- Medicine to ease pain and swelling
- Crutches to take weight off of the leg as it heals
- Exercises to help with strength, flexibility, and range of motion
Most strains are due to accidents. Healthy muscles may prevent some accidents. This may be done through exercise.
