Hello and welcome to Chat Doctor, In order to come to correct diagnosis, skin scraping and skin biopsy need to be done. Psoriasis is characterized by silvery skin scaling, bleeding spots after scraping the skin, rapid turn over of the skin, involvement of the flexes are the most common presenting symptoms of psoriasis. Since, the skin lesion is not responding to carbonate, a skin biopsy needs to be done. This will identify the disease involving the skin. Psoriasis can be diagnosed on clinical examination and on skin biopsy. If there is any evidence of fungal infection, the fungus can also be picked up on microscopy. Management will be decided by the result of the above-mentioned investigations. Consult your dermatologist for further work up. Thanks and take care Chat Doctor.
