10 Symptoms of a Hamstring Injury

7. Difficulty when bending the knee

Since the hamstring is directly connected to the knee, this may be a problem. Whenever you raise your leg or do any movement with your knee, the hamstring activates. All those regular, everyday activities may become problems. That's why it's best to sit back and take a look at the situation. Rest is a priority. Because of this, more problems may arise. Since one of the biggest muscles in the body is unable to function, your knee may crumble. All the weight may fall on it and cause an even worse injury.
