Hello,
There are many treatment options for psoriasis, chief ones being cognitive behavior therapy, creams containing coal tar, dithranol (anthralin), corticosteroids like desoximetasone, fluocinonide, vitamin D3 analogues and retinoids and phototherapy and photochemotherapy. Psoriasis that is resistant to topical treatment and phototherapy is treated by medications that are taken internally by pill or injection. The three main traditional systemic treatments are methotrexate, cyclosporine and retinoids.
So you can discuss these treatment options with your dermatologist. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
My husband got relief from the psoriasis in his ears by sticking to a gluten free diet. A certain percentage of psoriasis patients can blame gluten for their problems, but not all.
Look the diet up online and give it a try and see if it helps. Give it a few weeks to months to see if it gets rid of the problem.
