I recently had a hysterectomy on Nov. 19, 2014 and I have been having the worse lower back pain, as well. I can't stand or walk for more than 10 mins at a time and I've never had issues with my back before. I dance at my church and I haven't started back because I'm afraid the pain will kick in at any moment. I mentioned this to my doctor and he said "well, I didn't do anything to your back; I went in through your stomach." And I told him that I was not having any problems before the surgery. He could not offer any explanation but did give me a prescription for Motrin 800 and told me to do some back exercises and apply heat occasionally. Sad to say, nothing is helping :(
