FYI don't mix pills and vodka last time I did I woke up naked in a girls dorm
Better than in a boys dorm!
To the o.p., I have back pain and knee pain also. I have been drinking apple cider vinegar with honey and cinnamon for a few days. I will let you know if it helps. I haven't been drinking it long enuff to see if it helps of not. I will try tart cherry also if this fails.
