I am 23 years old and I have had psoriasis since I was 12. Unfortunately, I have yet to find any topical meds that are completely effective, but there are alot that help. I have had some luck with Dovonex, Psoracon, and Tazorac. The sun is the best thing for my skin- but I can't always get natural sunlight so sometimes I use the tanning bed, but of course you have to be weary b/c of skin cancer. Psoriasis is actually an autoimmune disorder, not a skin disorder(so I have heard)and can be aggrevated by stress-mine first appeared when my parents got divorced. You might want to find something to help you manage your stress. I have found Psoriasis Connections to be helpful-they have alot of good ideas and stories from other people who suffer from psoriasis- I think you can sign up by going to their website. Good luck and I hope you find something that works!
If it's psoriasis, surgery is not an option, since it will scare and make the condition worse. You cut out growths or cancers, not rashes. Lasers are an option, but there are simpler ones: stronger creams, injections of steroids, ultraviolet light. Ask your doctor. Psoriasis can't be cured, but it can be controlled better than yours seems to be.
Best.
