My father has knee pain.his work makes him stand for many hours. the doctor advised just to have more rest. but its hard for him to do so. advise plz.

Difficult when: Work is needed but pain is constantly there. I would suggest asking if there is anyway to sit during work. Assuming knee pain is basic osteoarthritis and not acute injury, try different shoes and include a lateral shoe wedge to offload the medial compartment. Also institute a strengthening program to work on quad and hamstring strength to support the knee. I hope employer allows position change.
