I am waiting to see a Rheumatologist and it will take a year to see one. They think I have Rheumatoid or Psoriatic Arthritis. I'm starting to think it may be Psoriatic because of the rash. I had the rash about 2 years off and on and then the arthritis symptoms started. At first I thought I had dermatitis and I was using moisturizers and petroleum jelly on my hand but it didn't really help much.
