I also haven't had an allergic butt, nor migraines of the butt, but I have had hemorrhoids, which are a pain in the butt - but not too bad.
I've had hemorrhoids to the point of needing surgery.
My main advice: if you aren't sure you need hemorrhoid surgery, you don't. If you need it, you will have no doubts about needing it. The recovery was two weeks of awfulness. But it worked.
