Hi calahope,
When I was in remission, apple cider vinager capsules (3 x 500mg from Webber Naturals at Costco) was sufficient to keep arthitic pain away. I have been using it since 1999 and it was working as long as I was in remission.
I'm in a Crohn's flare and on Imuran already; my GI added Humira. It seems to be working very well for the bone and joint pain as that all came back with a vengence... I avoided stairs and all walking as much as I could too.
Even if it's not advisable to use NSAIDs, these are the only things that offer me any kind of relief from any pain (headache, joint pains, etc). I am careful with these.... they aren't very good for us.
I also use "pain patches" as well, like the Salonpas patches. It works pretty well. They don't affect your overall system and help with targeted pain in a specific location.
good luck with the colonoscopy!
