Hi, I am 40 years old and a female. I am overweight. I had took some depression pills for one time event situation, I had lost my job than house and car. I developed psoriasis after the medication. Will the medication ever leave my system? I have psoriasis for 3 years. I have it on my scalp and flex areas. It just keeps spreading all over now on my legs. I am under light treatment and dovanex, tar shampoo, flue. hydro cream and other creams. I just recently have taken cod fish vitamins, this has help the itchiness on my scalp and flaking. I also time to time drink green tea with one spenda. What can I do to stop the spreading and how can I get rid of psoriasis from my body.
