osteoarthritis
"Meloxicam worked fabulously for the osteoarthritis in my knees/elbow/and shoulder. I noticed that I kept gaining weight so easily even with cutting back on my diet. It was unusual as I can usually maintain or lose weight. I looked up the side effects since I couldn't pinpoint any other change and read that meloxicam CAN cause 
rapid weight gain.  Since I cannot afford the extra weight with the bad knees, I am going to have to stop using it."
