Does Psoriasis come back?

And the chances are that it will go away from your penis, but will appear somewhere else, just be vigilant, 

Ok.  That is all Im worried about, that I can get rid of it on my penis.  I can care less if it reappears elsewhere, ill deal with that when it happens.  So it is possible to 100% treat on my penis, and once treated it may not reappear there, or may, there is no way to know.  But there is the possibility that it won't come back there once treated.
