Do you see a Rheumatologist at all? If not, I would recommend you getting a referral to one. Sounds like you have some Crohns arthritis going on. Could the pain in your back be in the sacroilliac area (low back/hips area) with the pain going down your leg?
And no you are not going insane:) This dd disease can really tear your body up and make you feel much older than you are. Sending healing thoughts your way.
