My husband has had a red rash that itches and burns for weeks. He saw a dermatologist and they could not give a definitive answer but prescribed some creams to put on. The rash gets alittle better but doesnt go away and then gets much worse again, We cannot figure out the cause but have change Tamulosin for Urinary and prostate issues. Could this cause a rash? He has had psoriasis in the past but this does not look the same.
