Hi Shawn2040! Could very well be allergies, by how you described it. Talk it over with your primary care physician(PCP) and see if he/she might refer you to an allergist, because only by allergy testing will you know for sure. The skin pricks on the lower arms are not so bad, the upper arm pricks do hurt. I don't think anyone tests on the back anymore. Good luck! Hope you feel better really soon
You'll get lots of good advise on this website. read some of the post they might help you out. Best wishes
