hyperparathyroidism & Post surgery issues

Has anyone else had the surgery to remove parathyroid tumor? Dr. Norman was our surgeon and was great,but its been 4 weeks and mom still needs pain meds 24/7 for knee pain,foot pain and continuous to have memory/thinking problems.Dr. said she had the tumor approx. 10 years. I'd like to talk with anyone who also recovered slowly from surgery. We need encouragement that she will get better from someone who has been there!
