About a year ago, I started experiencing sharp pain in my thigh joint (the area my life thigh joined with the upper limb, just beside the scrotum). The pain is very sharp often comes intermittently and lasts only a few seconds. After putting ice on the surface, the pain seemingly disappeared; but it appears to have come back again as I have experienced it intermittently between last month and now. What could be responsible for this pain and what could be the remedy? Should I consult a doctor?
