Hi there! I am 25 years old and I have been suffering from an itching and burning sensation on whole of my body. This itching was not there one month ago and I was perfectly fine but now all this has changed. I think I have been infected with psoriasis. My mother had been an arthritis patient herself so I am all the more worried if this could turn out to be psoriatic arthritis. I want to know the treatment for psoriasis?
