Hello. I have heard a lot about scalp psoriasis leaking a clear and odorless liquid. I believe I have scalp p but mine leaks a yellow liquid with a very gross smell to it. I went to the doctor not to long ago and got a prescription for medicated shampoo which seemed to help for a little while and then it would just come back. I m not exactly sure how to describe the smell other than it us very unpleasant. I m not sure what I should do. I just want it to go away.
