osteoarthritis
"I only have half the cartilage in both knees due to osteoarthritis and had taken 800mg of Advil 3 times a day for 10 years. I've been taking Mobic 15mg. for 2  years which provides very good pain relief with one pill a day. Sometimes I have pain in the evening for which I take 2 Tylenol. Mobic seems to be much easier on my stomach."
