I'm not sure if this will be helpful, but YouTube has picking and popping videos. Some people find them helpful in keeping their hands off themselves but still get the same "release of stress". For some it could possibly be triggering, but others really find it helpful.

Most people find the videos gross, but I think they are cool. Body stuff is trippy.

Either way, I can tell this is stressful for you and I hope you find some resolution. ((((Hugs))))
