Has anyone had this happen?

I was in remission for almost two months, but am now in a flare. I fell asleep on the couch and got up to take out my contacts to go to bed. As I was taking them out I got really really hot and started sweating. I sat on the toilet and went to the bathroom. I felt better after a few minutes of sitting there. Was this just random or a symptom of UC?

I tend to get really hot when/after I get up during the night to use the bathroom, sweating, etc. I have to kick all the blankets off till I cool off. I am a 50 year old woman though. But I do think part of it is getting up suddenly and the body trying to adjust it's regulatory system.
