I had my hysterectomy almost 10yrs ago, I am starting to get pain again in the lower back it feels like endo pain & im suffering with bowel movements as I used to before. Can it come back after all this time. I have also been on buprenorphine & tramadol through this period, could that have just been masking the pain? Would like your thoutghts on this. I have purposefully not taken HRT's either fearing that this would trigger the endo again!
