For years I had this rash on my right knee right on the side of it. Really itched like crazy. It looked like tiny little blisters they came by twos. they looked like little bites. I would scrach them and they would break open and the juice would spread and then i would have more bumps. I went to see many doctors no one knew what it was nothing helped it. I am now I am convinced its from gluten. Does any one else have these bumps?
