It could be from the steroids or it could be from the UC which can cause stiff/achy joints. I would give it a few more weeks to see if it gets better. I would think the steroids would be out of your system by now. I'm not sure about
long term damage though, anytime I'm on steroids, the pains go away after I'm off of them. So far I haven't had any pain except for when I'm coming off the steroids.
