Hi Brenda,
Welcome and I am happy that your found us.
I am sorry that you are suffering but hope your surgery goes well.
Its interesting that its connected to your monthly cycles.
Just a thought because I have been reading about this topic lately for myself and recently ran across some information that may or may not be applicable.
Has your doc connected this in anyway to Endometriosis? I just wondered because of the hysterectomy. If bad enough it can travel throughout the body and I recently read about a woman that had it and seizures as well.
