So i'm currently in bed with a rotten cold, and have been hugging a hot water bottle for the last couple of hours.
I just got up to get some more tissues and noticed i have a red rash under my skin on my stomach and lower chest area. It hasn't gone after 20 minutes, but I don't feel any pain or irritation. It doesn't even feel any warmer than normal body temperature.
Any insights on what this is? Or how/if/when it will go away?
PS- The hot water bottle is in a jumper-like material case and i am wearing a vest, so the rubber wasn't touching my bare skin, and it couldn't be an irritation to the material.
