Many UC suffers also suffer from Uveitis.

I personally have not had eye inflammation but I have seen members here mention dealing with eye problems.
I have never had rib pain with UC but I have seen a lot of members mention having dull aching in the abdomen. If you're in a solid remission, hopefully it is not related to UC. Always be on the look out for early symptoms of a flare. Mine usually start with gas and discomfort and are shortly followed by blood, mucous and increased frequency.
What medications are you taking? Many of us find that using enemas right when you feel a symptom of a flare can be helpful. Usually flares begin in the rectum. I use enemas and suppositories for maintenence as well.
