My name is Hemraj Jethanandani born in India and now a US Citizen. I am 87 yrs old , married, living with my Wife and Son in San Jose.In general having good health except had back pain for 5-6 yrs which subsided with physial therapy, regular walking . Since one yr however having pain in right thigh and knee.have stopped regular walking because of pain. Pain medication did not help. Recently consulted Advanced Health Care, a division of Coyle Chiropractic Corp who suggested nonsurgical knee decompression plus deep tissue laser treatment. was not impressed. appeared to be more of sales talk. My primary Doctor advised Physical Therapy and pain medication
