### input:
Four weeks ago, I went running--20 minutes later, it began hurting. It was enough to make me to keep the pressure off for a day, but I did all my normal activities with minimal dull pain. One week ago, my ankle swelled up pretty big. The next day I went to a walk in clinic, got an Xray, and the doctor said I was fine. He told me to wear a brace for a week. I have to walk back and forth to class every day (across campus, maybe a quarter to half a mile). The brace didn t give me any support--only made sure it wouldn t twist or turn on itself. The swelling hasn t gone down at all (it has been a week). Today it looks even worse, and standing on it has become unbearable. What should I do?

### output:

Hi, as you mentioned the swelling of an ankle, and your visit to doctor, x-ray, and brace. I see it more of an ankle ligament injury. That is the reason the pain is not coming down and also, you are having pain while standing more. Only an MRI can help us come closer to the issue. Ankle joint is the one first joint to bear the whole body weight so coming close to the diagnosis will be of choice with the help of an MRI. Also, rather doing all these, Try to pick bits of paper with your toes from the floor. It will help strengthen the muscles of feet. Also, understanding the biomechanics and pathomechanis of the foot is a wide area to explain, so care is important even in the smallest cases. X-ray can only show the bone, but the MRI will show the Soft tissues as well. I hope to see you, if you have any personal questions to ask.
