Warm Patches

I've had something pop up the last month that I wanted to see if anyone else experienced. I'll have these periods, not lasting maybe more than five minutes, where a patch of my body will feel warm. Like for example, yesterday the front of my leg between my knee and foot had this very warm feeling (warm, but not burning or anything) for a few minutes and went away. It's peculiar because it's new, and I'm a ways through my recovery (10 months). Anyone else experience this? Thanks!
