i get the same exact thing but i break out in hives every now and then and they itch like crazy and when i get outta the shower i wanna scratch my skin right off my body sometimes, and by the way im no evan on anything, and havent been in along time. Ive seen many doctors for this and they have no clue what there talking about and can never give me an answer whats goin on, they just give me lots of pills and tell me come back in 3 weeks. the only thing they keep saying is that this is common when something at some point in time got in your body and your body doesnt like it and until your body gets rid of it , it wont go away. So it could be the roids but like i said im clean and it still happens soo... And also they said wen your extrememly stressed out and have high blood pressure, so you might wanna get your B.P checked also.
Hope i helped
