what type is this, and how can i get rid of it :/

I came out in Guttate psoriasis (after having been virtually clear of plaque psoriasis for years). This erupted 4-6 weeks or so after a hip replacement. My GP at the time, who seemed quite knowledgeable and was certainly helpful, advised that it would probably go away after 6 months or so. Actually it took 8 months. I used Exorex Coal Tar treatment, and Psoriderm lotion where I could reach. I did not want to use steroid as the guttate psioriasis lesions were so small and numerous, and I did not want to slather topical steroind over all the good skin between the lesions. The itching drove me mad and the best thing I found generally for my arms and chest was Doublebase Gel, and Doublebase Dayleve Gel. I just used those over an ovr during the day. In the evening a mildly warm bath with Oilatum+ bath oil additive calmed the itching well enough that I could sleep. I spent a fortune on other creams and potions but these were the ones that helped me. For my scalp - Alphosyl (now disconrtinued) or Polytar shampoo, or Alphacade shampoo (excellent and pleasant). Again I spent a lot of money on other things to try -without any success for me.
