i started getting these red blotches on my arms and hands more frequently lately,ive had them before but the werent to the point they are now. They vary in size,there itchy and seem to throw off heat and have an irratating burning feeling to them,some of them seem that they are a bit raised from the skin,and if there is alot on one arm the whole arm seems to ache. I have no idea what they are! but they are driving me crazy! i have a picture but i guess i cant post it...
