I need complete knee replacement, but haven t been able to afford to go into the hospital to get the procedure done. Had a set surgery date in early March, but doctor and hospital required too much up-front money for me to do it. Now, for the past 3 weeks I have been in severe pain in my lower back (also left side), down into my upper left buttock. Can t hardly stand, can t hardly walk, and can t hardly sleep. My family physician thinks it is joint pain and has prescribed Meloxicam, but it is not working. Can my lower back be killing me because of my left knee being out-of-line??? Thanks, Patty Hullett
