I had rhizotomy in my right buttocks/sciatic area two weeks ago and it's still numb in some areas and very sore especially when I sit. My family has had this done on many occasions and say it can be pretty sore for up to 6 weeks because of swelling. I see a small bruise which is normal as well. I've been taking it easy, but its hard to take it easy when that requires sitting! I'm trying to think of a future with less pain and that helps me be patient, as my family members who suffer from neuropathy/piriformis syndrome say it's well worth it.
