My grandmother has horrible pain in her knees. She needs a knee replacement, but she's almost 80 & doesn't get around too well. She's already been through heart & back surgery w/in the past 2 years & doesn't want to go through another surgery. She also has constant shoulder/arm pain. The doctors told her that her rotary cuffs (I think that's how you spell it) are worn away. I want to know is if there's anything that can help her. She tried some meds, but she gets sick from them. Surgery doesn't seem to be an option. Any advice you may have would be appreciated.
