I have had mild/moderate ulcerative colitis my entire adult life (in my mid-50's now). My last bad flare was almost 2 years ago. After that, I developed some patches of itchy skin on my knees and elbows, and am increasingly experiencing joint pain. I now suspect psoriasis/PsA linked to my inflammatory bowel disease. My question is - where should I start to seek treatment? My gastroenterologist? Dermatologist? Rheumatologist? Honestly, it's the joint pain that's affecting me the most...
