I've white dry skin patches. It was only a small patch in my scalp initially, so we thought it was just dandruff. But it spread over time. Now it's all over my scalp, my neck, my back, my front, arms and legs. Everyday I notice a new patch forming somewhere and it's super itchy. Doctors here said that is psoriasis. But none of the medication seems to be properly working. The moment I stop with the medical creams, the next day it comes back. The patches under my shoulder also burns sometimes.
