Rectal inflammation can have associated upper gastro symptoms. Food going through the digestive process will cause gas and depending on how much gas and where it's pressing, it can cause upset stomach.
Too much acidic or fatty foods can cause upset stomach and gas.
UC in itself can have symptoms of upset stomach and gas.
So, since you took the Rowasa last night and had new symptoms, I'd say it's the Rowasa. It'll create more pressure in the lower part of the colon because it's got "volume" and would create discomfort here as well as in the upper gastro area if it triggers some sort of a peristalsis reaction (since the system works together).
I hope it doesn't deter you from using them consistently at least to give them a fair chance.
I'm thoroughly impressed you held it in all night....WOW!!! you're off to a great start.
Hang tough....there are times when I use the Salofalk enemas and still get that feeling depending on how much gas is in my digestive tract.
An antispasmodic helps a lot...I use dicyclomine.
