Hi Asia,
My auntie said the same thing about Celiac tests - that you can get negative results but still have it. Right now my colonoscopy is tentatively scheduled for the week after this one. Before these symptoms showed up, I have always had one kind of allergy or another - my immune system is wacky. I know I have strong allergy to dairy (if I have raw milk, it can result in anaphylactic shock) I cannot tolerate direct sun and have allergies to some medications. I've been reading that UC can come on after prolonged stress too, and I've certainly had that. Last year I had a nasty attack of shingles that was complicated by aggressive infection that wouldn't respond to antibiotics. Long story short, it was a close one. I was on various medications for months. It was gruesome, and the scar (faint now, with treatment) caused enough misery on its own. I have noticed that when I'm happier my symptoms are fewer; and i NEED my exercise. I've found it makes a significant improvement on my overall condition and I have noticed that there is less blood when I'm physically active. Good luck, and hope your remission lasts!
And Jessica and everyone; thanks for the kind words! I may have been scaring myself by reading too much on the net but I am still really glad that my 'research' brought me here.
Thanks again :)
