If knees hurt when i jog, should i give up jogging? (i went to ortho surgeon 8y ago when problem began; he felt the knees and said no need to stop)

Could be many things: depending on how much pain is limiting your ability to function, you may need another evaluation from a physiatrist or a pain physician. X ray will pick up fracture and may be arthritis MRI will pick up soft tissue and ligament problems at this time, i would use NSAIDs and ice/cold compress and Physical therapy. In regards to exercising, I would recommend swimming as to avoid further stress
