Eval. Foot pain too: You need to be evaluated for your foot pain also. Sometimes it can be related to the knee arthritis. Often times people compensate for pain in their lower extremities which can cause pain in the general area where I think you are describing, but the foot pain may not be related as well and may have to do something else. For work up of your foot pain see a podiatrist or foot & ankle specialist.
