I'm 40 and I have suffered from severely swollen knees for over 10 years. I have seen an orthopedic specialist/sports medicine doctor, had X-rays on both my knees and have been told "surgery is not the answer" but anti-inflammatory medication is. So I have been taking the recommended 1200mg of Ibuprofen nearly every day for the 10 years they have been bothering me. And when I tried to decrease the amount, they swell up like balloons and I can hardly walk without moving in a crouch to ease the pain.
