Drugs
After not biking much for for a while, this past year I started riding regularly. I have minor re-occuring knee pain. I have found that the Glucosamine has been very helpful in preventing pain. I equate it to oil on the tin man. My joints are approaching 50 yrs. Please follow the previous posts advice and ensure proper bike fit AND get checked out by a doctor. Knee mangement is a fact of my life, which includes proper bike fit, trying to spin at 60 rpm +, avoiding extensive honking (especially early in a ride untl I am well warmed up), knee rest days and the irregular use of ibuprofin (anti-inflamatory) and the glucosamine. Good luck with your knees.
