What is a mental health condition where a person compulsively picks or scratches their skin?

I think my brother suffers from this illness, he cannot get help from doctors or psychologists. I am at my wits end trying to get him help.

I also have this condition. I wish that I could stop it. But it is really hard to quit I also have BPD

I do this didn’t know it had a name I also have depression

Alison, Sadly true...

jay, I'm sorry to hear that 🥰

Or the condition of a crystal meth binge 🤪

I didn't know that this was a think I have been picking my skin for as long as I can remember
