I have had a rash for 7 years give or take. Its on the back of my leg and it stretches to the middle on the back of my knee.Recently within the last year it has spread to my ankle. Sometimes it blends in with my skin, other times it can be red. Ankle rash does not blend it. It itches sometimes, really only when Im thinking of it or I notice it. No where else is there a rash, just simple break outs on my shoulder but it comes and goes and it looks nothing like the rash. Again ive had this for 7 years. Its bumpy but it does not have sores on it. Looks scaley. I have never mentioned it to any doctor because when I did go I never thought of it as a kid, as I get older it seems as if its spreading more.
