New member and new diagnosis

i am new to this group. newly diagnosed. just had a second round of biopsies and will no for sure on Monday. why is it so hard to diagnos? I am 67. I have MS and hypothyroid. Don't know if there is a connection. my body is covered. Not my face!!! Did it take anyone else a long while to get a confirmed diagnosis?

Welcome. Are you referring to psoriasis?
