Currently, I have pain in my right thigh. There is a circular shaped patch of red towards the middle-inside of my thigh, and an offshoot of the same color (as though I had been rubbing the area) that leads from the circular area to my groin area. There is moderate pain when any red part is touched, but no pain otherwise. The skin feels slightly warm (I say slightly because I am not entirely sure), and appears to be raised slightly (again, it is hard to tell). What do you think the cause of this may be, and what can I do to help it?
