If I had Pityriasis Rosea before is it definite that it may come back again? - pityriasis look like

I was with pityriasis rosea diagnosed a year ago. All healed well, but I was paranoid when I see something that a "patch may seem" too, or if your back itches. I have one that looks like that to me and asked me some time ago?
