DEAR DR. ROACH: I'm 69 years old. I take no medications, and I'm in very good health. Fifteen years ago, I had a hip replacement and now it is starting to squeak when I walk.
It is a ceramic socket and a titanium ball. Is there any kind of cream I can rub on my hip or an injection I could get to lubricate the joint? When will I know that I absolutely have to get my hip replaced? - P.F.
