I Am A 63 Year Old Female Waiting For A

I am a 63 year old female waiting for a total right knee replacement due to severe osteoarthritis. I have suffered with this condition for about a year. I am in constant severe pain & take no pain meds except motrin & tylenol 3. I cannot sleep & can barely walk with the assistance of a cane & walker & brace. Is there anything I can do to get some relief until March when my surgery will take place? My email is: YYYY@YYYY . Thank you very much. Kathryn Conley
