During the past couple days, I got this wierd thing on my elbow, I went to the doctor and he told me it was P, and gave me a prescription for Psorcutan, some sort of Calcipotriol cream. Today is my first day using this stuff, and it itches like crazy. Can I scratch it? What's the best way to get my life adjusted to this? How should I start dealing with it? I'm already on a low carb diet, should I take anything else into consideration? I would appreciate any kind of pointers, ideas what I should do for the short run and long run.
