How symmetrical is your psoriasis?

[ccarr06]

I actually hadn't put much though into looking at the pattern, but now that I'm looking, mine is quite symmetrical for the most part.

If I have it behind one ear, the other one flares up soon after. I have it on my both elbows, on and under both breast, and both cheeks and eyelids. I got a new patch on the side of one thigh, and the other one got a patch in almost the exact same spot within a couple of days.

Strangely enough, I normally get a tiny patch on my left eyebrow only, but in the last few days, I also got on on the right eyebrow.

I wonder what it is that causes the patches to be symmetrical like that!
