Well, I do have good health... But recently I have got red patches on my skin. about the size of my thumbnail? These dont seem to be insect bites...they are red, and slightly dry and scaly. You can feel them with your fingers if you know what to look for. Also though free of pain and irritation they are `very slightly` tender. On my belly if thats a clue As far as I know I have not been in an environment that might aggravate my skin.
