keratosis
"AK on my left cheek. Laser treatment in 2011, then in 2 years AK came out again, from boundaries of laser treated area. Went to new dermatologist, who prescribed Aldara but did not tell about side effects. After 10 days treatment, skin in AK area was badly affected, really effective. Then I had a night with drinks etc. and immediately after that, started persistent influenza like symptoms I never experienced before during summertime, as well as diarrhea. I went for info online and understood it was Aldara.  I stopped anything could weaken my immune response, had plenty of sleep, vitamins, healthy lifestyle and continued the treatment. Stopped after 3 weeks. Side effect gone, big crust, new skin after one month, no more AK. Great."
