Question about my injury. i beg of you?

First, it has to be examined by a doctor and he will determine what is wrong. Hopefully, you are taking some pain medication (ibuprofen or tylenol) on a regular basis for the pain. After he has determined what he thinks is wrong by his exam, he may order an x-ray. Then, after putting the pieces of information together, he will decide what is the best way to treat this (if a sprain - pain med; if tendonitis, maybe anti-inflammatories; if torn tendon - maybe surgery; maybe any of these with crutches). It all depends on what he finds. There is no way to tell on this forum.
