I had j pouch surgery as a teen and now in my early 30s I am already developing arthritis nodules on my fingers. They are becoming noticeably more crooked every month. I know we have all been through worse but it’s genuinely very upsetting.
If arthritis starts early in life I would assume it progresses faster & inevitably causes suffering for a significant portion of life. Nobody else in my family has this therefore I would suggest it is related to IBD/autoimmune disorder.
