hello. i am a 26 year old filipino male with an annoying rash. at first it was diagnosed as PR, and was said to go away on its own within a few weeks, 6 months at most. its been over a year and a half, and when i followed up with my doctor, we took another skin biopsy and it came back as spongiotic dermatitis . he said for whatever reason it morphed into this new symptom. I find that hard to believe as he couldnt explain to me how it happens. i ve used cortizone creams, calamine lotions, and calming itch relief lotions. i found the lotion that has helped best with the mild itching and bumpiness to be cetaphil skin cleanser . eucerin and others make my skin feel too oily and more itchy. ive changed my diet, my soap, and ive started to work out thinking it was my health causing it. yet, it still all over. after showers and times when i perspire under heavy activity ( usually at work as i transport patients to and from radiology) i feel a needle and pins sensation over the larger regions on my torso . i notice in the mornings when i first wake up, it is not as noticable, but as the day progresses, the rashes maintain a dark reddish color, and are bumpy to the touch. legions centralizing all around my torso and back and upper thighs and biceps. it doesnt reach my neck or chest , but i have spots or spottings (not legions) down towards my feet. what is this ? im thinking an allergic reaction but cannot verify.
