For about a year I had noticed a very small (about 2mm by 4mm) patch of rough, scaly skin under my right eye. Sometimes it would heal up, but mostly it was slightly rough and red. I was pretty sure it was a small patch of acitinic keratosis, a skin condition that can develop into skin cancer if untreated (pretty common in the over-40 blond/blue-eyed set). I’d had them several times before in the same general area, and each time I’d gone to the doctor I’d been treated with cryotherapy (a tiny spritz of liquid nitrogen). After the treatment, the area would scab up, and when the scab fell off the skin would be pink and smooth underneath.
But … I didn’t feel like going to the doctor’s office. With my broken foot and gastritis, I’d spent far too much of 2017 in hospitals and doctor’s offices. So I did an internet search to look for alternatives.
