Greetings all. I am trying to determine if I have psoriasis or not. 4 yrs ago i had a round spot on my right shin. My doctor thought it was possibly cancer but tried creams first. It spread rather than clearing up. I moved from one province to another then so started with a new doctor right away who scoffed at the notion of cancer and said it was just eczema and to moisturize heavily. It spread to my other shin and I have two very large oval patches. I have bought and tried so many moisturizers... with no success. I have ruled out cancer because I don't believe it is cancer but i am not sure I believe it is eczema. The areas seem like they are producing large amounts of heavy scale or skin - like a crust. Any suggestions out there about how to determine what condition i am actually dealing with? I do need to go back to the doctor I know... thanks for your help.
