Bill, My mom had a hip replacement and had a great deal of trouble following the anesthesia and surgery (it was an emergency because of a bad fall in our driveway). When she had it redone, the doctor used a localized anesthesia and a drug that would make her forget the whole experience. Her recovery was amazingly fast. This was 10 years ago and the doctors tell us that they have improved the anesthetic drugs greatly. (She just had cataract surgery this summer.) She also has had swelling and it has been the result of various drugs (mirapex caused the problem last year). Today we learned that the Vioxx might be the culprit for her recent edema so we are switching to Tylenol Arthritis. She does not have arthritis but aches because of the rigidity. Hope you get some helpful answers when you visit your physician. Take Care, Robin, caregiver for mother Peggy (age 79, diagnosed in 1980)
