After cycling or sitting in one position for a while i get pain on and around my knees. sometimes the thigh muscle just above the knee has inflammatio?

Arthritis?: Knee pain, inflammation of muscle, and problems with exercise (cycling is not weight bearing) requires a review by a musculoskeletal physician (orthopedic surgeon, physiatrist, or sports physician) to care for the knee and support your active lifestyle. X-ray and lab work may be helpful. Try tylenol (acetaminophen) or liniment for comfort. Wait on arthritis medication if you have high blood pressure.
