Just the past day or so, I noticed a slight burning feeling on my left thigh. At first I thought it was because my phone was getting too hot in my pocket (that's happened before and it's in the exact same spot where my phone would be) it today I was noticing it but my phone isn't in my pocket. It lasts for a few seconds then goes away on and off. I don't feel anything else like pain, spasms or anything like that. When I touch my skin it doesn't feel any warmer either.
