I sprained my foot while playing football five years ago, and the swelling went down a month later, but I still feel that my hamstring is in the wrong position.

First: I have had similar injuries. The problem is that you are not completely upright when you are injured or you don't pay much attention to protecting your right foot when you think you are better.

Second: Generally speaking, this kind of injury does not require surgery. When playing badminton, I feel that my hamstring is seriously dislocated, which is my psychological function. If it's serious, you can't even walk. This situation should be that you did not warm up enough and hurt your hamstring during strenuous exercise.

My suggestion is that you go to see a Chinese doctor and recover through physical therapy, massage and massage. There is nothing wrong with walking lightly, but you will hurt your leg if you encounter strenuous exercise. You must go to a big hospital or a famous doctor to see Chinese medicine. They usually look at it accurately, and they can know your situation by touching it. Stick a few Chinese medicine stickers and there will be no big problem. If necessary, you can also acupuncture. For the injured leg, you can't do strenuous exercise in the near future, and it will hurt your muscles and bones for a hundred days. Be careful at ordinary times, not careless. After a long time, you can gradually increase the amount of exercise. In rainy weather in the south, my legs will feel a little uncomfortable and it will take a long time to recover. I sprained my leg at that time, and I suffered from rainy days for four or five years until recently. Maybe I'm old, and when the weather is bad, my legs are as uncomfortable as yours. You don't want to have too many shadows in your heart, talking about surgery. Of course, if it is really a serious hamstring tendon tear, it is needed. Take an x-ray to judge whether you are not at ease. But to sum up, what you said is only the pain when squatting, and I guess it is also strain. I can see that you like sports, but this matter can only be done step by step and slowly. I hope my answer is helpful to you.
