I did have temps, running from 100-102. If it's below 100, it's hard to really consider that a temperature (it can fluctuate over the day up to the mid-99's), so if I were you I'd only count the ones that rise above 100.
They are tricky because just like you, my docs couldn't figure out where they were coming from. They made me feel just gross all over. I took Tylenol like candy most of the time. They thought I had IBD, but couldn't find anything grossly inflamed in there; they thought it was parasites, which made more sense, because I've traveled to a ton of developing countries and have gotten sick with them in the past. That's when they put me on Flagyl, which helped a lot. Still, there's no real resolution.
If you are in a lot of pain, a lot of serious acute rolling-on-the-floor pain, call your on-call doc, or go to an urgent care clinic or the ER and they'll be able to give you IV pain meds. Try to stay away from the NSAIDs (non-steroidal anti-inflammatory drugs) like Motrin - they have the potential to make your guts bleed.
