I m diagnosed with autoimmune decease sjogren syndrome since 2018. I have small circle or oval shaped itchy patch on nose, above chin and area between nose and lips. It develops patch, dry hard white cover and shreds and then come again. Under white layer there is red skin. It gets active in winters and i m suffering since 2012. I did show to doctor and he said these are warts, but homeopathy of warts didn't work on it from 8 years. It burns in winters alot. I m tired now. They come on same place. I have 5-6 in total. I googled it, i think i have psoriasis or actinic keratosis. Please guide me, i m tired now.
