I found a large area of mold behind the refrigerator on the floor where moisture was driping and in the condensation drip pan. This is in addition to the large area of mold I found under the sink last week from a drip leak as well as small amounts in the shower area.
I killed all the mold with a bleach based cleaner.
All my symptoms have now disappeared. I haven't had to use vaseline or any other cream in the past week. No more peeling flaking or recurrent canker sores.
Now why couldn't one of the doctors have told me 8 months ago mold could be the cause...
