I have been cursed with Psoriasis

[Fred]

Anyways I do have a question, that maybe someone could help me with. This issue occured for the first time, back when I am on Humira. I get these small bumps underneath my arms and continues down my lats. They eventually scale (hurt when itched) and disappear. My derm said not to worry about it, but they came back after the last shot of stelara. It didn't last as long as the first time, but I am somewhat scared that it might be related to the drug.

When you say bumps, how big and do they have any substance like puss come out of them ? If so it could possibly be Pustular.
