What are some ways to alleviate relieve knee pain?

Medicines, PT: Let's assume this is from osteoarthritis (wear & tear) and this advice (like all advice from this site) must be discussed with your md prior to starting. I prefer topical nsaids (voltaren gel) as a 1st line agent if there are no contraindications. Many patients find this enough for their pain. Oral meds (tylenol (acetaminophen) and tramadol) is 2nd line, followed by narcotics. Then physical therapy would be next.

Exercises: Exercise therapy can be very helpful for knee pain, particularly runners knee. However, they must be performed in certain ways. Rest from strenuous activities and targeted therapy are key. Online resources are available on sites such as simpletherapy.Com.
