Let's put it this way. I'm 310 pounds (fat, not muscle), 6 ft 2, and 16 years old. I was reading on the computer and scratched my stomach, and felt roughness. I Looked and my skin was peeling around a large area, close to the pelvis. If you've seen an overweight person, it's under my stomach. As in, where the fat stops--it hangs a little (gross etc I know) anyway, The skin is peeling, and is dark colored. Any idea what it is, or how serious?
