I've been using copaxone for a little over a month and two injection sites (left stomach and left thigh) have been avoiding both sites, but the one on my left thigh is a red lump with purple speckles that is solid, itches like hell and has grown to about 10cm and is rock solid. I can't get a doctors appointment ahead of 3 weeks, what should I do? It really hurts, like achey and burny at the same time, am worried :'(
