I've never heard of RSD spreading to a uterus, but maybe others have.

I know how you feel, as I had similar issues for two years before my recent hysterectomy, and my pain went up when I had my periods so it was a big nightmare, that is thankfully all over now. Mine wasn't related to my RSD, it was a separate issue believed to be a byproduct of getting my tubes tied when I had baby #4.

Hopefully some others can offer you some insight on this, and I'd ask your pain specialist what he thinks, but from my understanding RSD can't affect your reproductive organs. I hope you get to the bottom of it soon.
