Before demo diagnos with PN, she told me I had a picking disorder. I
Know what your feeling, now she tells me I have PN, and don’t pick,
She suggested I see a therapist.
I would love to see another dermatologist, the list around my area is slim
I don’t think they are taught compassion.

No, I haven't. In fact my dermatologist was bound and determined to diagnose and treat the issue of my skin. So greatful to her and her support team!

While I have been diagnosed with PN, my dermatologist did still ask if I was a nervous person or a known skin picker. The implication that I've done this to myself was very upsetting. I understand that I must leave the nodules alone if I expect them to heal, but I seriously believe the nodules arrived at the same time as the itching. Let's hope future research discovers more about this. I don't doubt there are skin pickers out there, but only you can conclude if that's true in your case. Just keep seeing new dermatologists until someone with compassion and understanding will help. I've gotten so used to the itch after 3 years that most days I don't scratch my nodules at all. Still takes months for them to flatten to nothing.

That is the easiest complex question and answer! Some listings and people (medical) still state PN is a picking/scratching problem, maybe due to mental issues. No, I'm not going off or crazy, many have been told this... First thing is, are you taking any antidepressants..?
I have listed Derm. issues .. but some still address the scratching as though I willfully wish to scratch in my sleep, or when I'm around other people, even if on zoom. That's from stress & anxiety.
Before PN was diagnosed, I had no Derm. issues. After PN, I now have a few badges on my chart, including dermatitis, eczema, rosaceae.
I hope you get to the bottom of yours, whatever the true 'thing' is, or combination.
