Can you post photos of your skin? I am truly curious as to what this looks like.
I think you have hit a dead end here on Curezone. I don't think it's healthy to keep up these posts asking for a diagnosis. I think you need to go to the doctors who have labs and instruments and machines where they can do lots and lots of tests to diagnose you. Even if you don't have the money, there are ways to get it done.
I seriously would like to see some photos. Maybe some professionals on these forums could get you leads by seeing some visuals.
