For the past couple of days I've been having this burning sensation/itch on mostly my right arm. Sometimes I'll get it in my right arm and thighs as well. There are no scratches or anything *aside from this little tiny red bite or mark I have on my arm* but anyways, it feels like a sunburn on my arm and sometimes hurts and burns when I touch it. Do you guys know what this can be? Is it possible that it could be from my clothes detergent? I just switched recently and im thinking maybe that could be the issue? Also, I've been wearing the thermals *for winter* under my pants and shirt to keep me warm and they are cotton, and it seems when I wear that I burn and itch a lot more.
Any help would be greatly appreciated. Thanks.:)
