I do find when I'm on pentasa, I get rashy, dry scalp, bad breath, generally feel dehydrated even though I try and drink lots of water, but those are obviously insignificant compared to a flare.
They are significant if you are in remission. It may be worth experimenting with different mesalazines to see if you can find one which gives you fewer side-effects.
Also, lack of ulcers doesn't mean it can't be UC. It just means the inflammation hasn't been severe enough to progress to ulcers; ulceration is the last stage of inflammation. But after 9 years you are overdue a scope; definitely time to get another one.
