Hip replacment , gall stones and using vibrating machine.

Patient: I had a hip revision 13 years ago and I also have two large gall stones. I bought a vibrating machine in October and have been using it 10 minutes a day. I actually feel better and it hasn’t caused me any pain. The nurse in my doctors office said to go ahead and use it if no pain, but I’m wondering what the consequences could be.

Doctor:
