So i went to the doctor the other day. i have these clumps of really small bumps on my arm. the doctor went to go seek a second opinion. they said it was nummular eczema. i looked up pictures online. i couldnt find a single picture that looked like what i had on my skin. the doctor didnt even do a skin biopsy. she just felt it, and asked me where it was. only on my arms. what do you think i have or do you think the diagnosis is correct? the clumps are about the size of a quarter and smaller. there are a lot of tiny bumps. they feel grip tape on skate boards, just bigger bumps. they are skin color. the same color as my skin. one day i just noticed them and there has been more and more. on both arms. doctor gave me prescription but it isnt working. been about 2 weeks, and there are more since the visit. help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! they dont itch. they just bother me, because my friends are starting to notice too!
