It depends: We need to establish the diagnosis before treating. Doctor will run some blood tests and x-rays before jumping on to the medications. I would recommend you to see your pcp.

Maybe: Glucosamine sulfate has been shown to help large joints to some degree but very modest results. Traditional anti-inflammatories have a better track record. Best bet is to start with flexibility, exercise and tylenol (acetaminophen). If your knees are causing a lot of distress have them checked out by your pcp. Good health.

Evidence Lacking: The use of glucosamine chondroitin is a very popular over the counter supplement that many people take for osteoarthritis. Research is mixed on its efficacy. Some research indicates that the glucosamine sulfate version may be the one that works. Often people look towards the more expensive combination of glucosamie and msm. It would be good to see an orthopedic physician.

Knee pain: Depending on age and risk factors osteoarthritis could be a possibility in this case .A common cause is patellofemoral syndrome which usually can be exacerbated when bending knees, standing up from a prolonged sitting position and climbing stairs. Osteoarthris is more common after prolonged use so tends to happen more in older folks. Glucosamine has shown modest improvement in osteoarthritis
