I was referring to the photos at the bottom of the article
I don't want to sound like a Pollyanna about your problem, which of course is terrifically painful in a very sensitive spot. But I've got psoriasis (a spot on my scalp), and I'd be entirely willing to have even a painful biopsy if it would take the whole thing away and it would never come back. It feels constantly raspy and scaly, and looks awful if the wind blows my hair away from it. It's just constantly irritating. I hope your psoriasis is gone for good, and your pain will be worth it in the end.
Good luck with getting more information about a safe painkiller. (As you know, people do get hooked on opioids, so be careful about what your doc prescribes.) Have you tried just the run of the mill pills for pain, like Tylenol or Advil? Sometimes one of those will totally surprise you by working.
Is that the doctor who did the biopsy? If not, did you speak to that doctor about this?
