Hi, I have been told that I need a knee replacement over a year ago. The pain has been getting progressively worst. I have been getting steroid injections every 3 month, which helps for a few weeks, I have been taking lyrica, which helps, but I sleep alot and can not drive. Any other suggestions, other than a knee replacement. I am 54yrs old and have been on several meds. Nothing works but the lyrica. thanks
