Hello Lisa (@techi), I'm sorry you not getting a lot of answers. If the doctors are in the same network you would thing the health records would be available for other doctors to review when they have your permission. I get a lot of scrapes and scratches that I sometimes don't notice right away. Mostly mine are when I bang my leg or arm into something when I'm not paying attention. There are some medications that are known to cause psoriasis. Here is some information from the National Psoriasis Foundation on this:

Here is the FDA Drug Recalls site where you can look to see if your medication is on the list:

Keep asking questions and pushing for answers from your doctors. You are your best advocate.
