Hello @fessenbeck65, I would like to add my welcome to Connect along with Pam @pb50. Just wanted to touch bases to provide a search link of Connect for "PMR + prednisone taper". You can tweak the search terms to find others with similar conditions.

It is really great to hear that you are still in remission after such a long bout with Pemphigus Foliaceus. Do you mind sharing how you found Connect? Are you trying to find some answers or others with similar symptoms?
