What can i use for psoriasis flare up under the left breast? it is very itchy and the skin looks bad

Dermatologist: There are effective treatments for psoriasis, but you need to see a doctor, preferably a dermatologist for and evaluation and prescription. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
