This just started about a month ago... I can be sitting in my chair and I feel like I am sitting in front of a heater. I am not hurting from muscle strain or use. I have had issues with inflammation for years. This is new.

I have never had those feeling... I just feel like I'm surrounded by a heater.

I wish I knew, as I will get a feeling of hot electrical feeling that will run down my spine and then go away. I also sometimes will feel like water is running down the inside of my arm and when I feel it - its dry.
My tests came back with no inflammation in me

I get the same thing and it usually when I am swelling the heat can get unbearable at times

i believe its inflamation, thats what i've deducted from years of dealing with this. with me the pain causes my muscles to feel 'hot' sensation to push on them but i dont have a temp.
