I have heard people say that they didn't come upon having PsO until something tragic happened in their lives.
It could be mental or something such as strep throat, or even some sort of accident. Most people will argue that it is a genetic disease, but so far no one in my family has come through to say they have it. I am 65 now.
Is there anything in your life that caused your psoriasis? We would love to hear from you.
