Hello XXXXXXX
Thanks for posting your query.

If it hurts in your knee, a back problem can give you pain there, just because the spine sends signals down all leg.

Medications: nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and pain; muscle relaxants; and pain killers.

Cold/heat therapy

Spinal injections

Physical therapy: stretching to increase flexibility, therapeutic exercise; posture and importance of maintaining good posture at rest, work, and during other activities.

Alternative therapies, such as acupuncture.

I advise you to visit orthopaedic surgeon for detailed examination. You may get the X-ray of the area affected under his/her guidance.

Hope I have answered your query. Let me know if you have any more concerns.
Regards
