Re: What does it mean when someone says "I am in a Flare for X months"
Yeah, it is hard to figure out sometimes. To me, "in recovery" is different than "remission". In recovery means healing, on the mend, headed in the right direction, getting things under control. Remission is completely symptom-free and on a stable maintenance drug.
Also, those of us who have had really bad flares in the past have traumatized intestines, which can often lead to irritable bowel syndrome (IBS) even when we're not flaring... IBS is pretty harmless, but the symptoms are almost identical. So sometimes when I am in recovery, I still have some IBS symptoms that resemble my ulcerative colitis. The only main symptom that I know is different between the two is blood. If there is any blood involved, then I know for sure it is ulcerative colitis. There is also blood test the doc can run called "C Reactive Protein" that measures the amount of inflammation in your body. Normal is 0-9 (the lower the better). When I was at my worst flare, my levels were right around 50, but when I'm pretty much in remission they are somewhere around 3. So you know if there is a lot of inflammation, it is probably the disease. If there is little to no inflammation, then it is probably just IBS.
It would be practically impossible for someone else over the web to be able to say whether you had a short remission or if you were flaring the whole time. You would have to analyze your own symptoms and compare them to times you know you were in remission or before you got the disease. It's possible you may not ever be able to get a solid answer. But we do know when our symptoms are bad or good, and which direction we want them to head... Good luck with yours!
As for your other question... It depends on what meds you are on. If it is just mesalamine (brand names Asacol, Lialda, Rowasa, Penasa), those are pretty harmless and shouldn't be causing temperature changes. But if you are on Prednisone or any immunosuppressants (Imuran, Remicade, Humira), then those could definitely affect your temperature, heart rate, etc. The side-effects are not fun, but they are better than the disease.
