I have had this condition for years now and I am just figuring it out now. Self diagnosis through research. This condition for me usually starts late summer and goes through the winter. Usually I get a break in the spring and early summer. Not this year. Worst year ever! That is when I started really trying to figure out what was really causing this. I have had x-rays indicating 4 different problems with my C5 & C6 vertibrae. Previously I have seen dermatologists and had light therapy. Used lots of different creams and steriods and nothing really helped. I recently emailed my doctor about trying Gabapentin after reading that it may help. It is helping a bit, but I'm still suffering. Ice is the only thing that helps, but when you have a break out on both arms in several locations at the same time it makes it hard to ice.
