I have a Coleman portable hot tub and got in the other night for a few hours when I got out I noticed a white spot on my belly that was red around it. Tried to pull the service off because it looked like a scab but it's definitely not. Has anyone ever seen this. It's starting to hurt terribly. To my belly I'm able to see the shadow of it inside my stomach.
