In the past 6 months my right knee is giving me fits. The pain in on the inside of the joint and begins to hurt after only a small amount of walking. It also appears that walking downhill is worse than up. I have used ointments and heating wraps and leg supports and all work a little but just temporary. I do have some stiffness in the morning and on and off during the day. I am 75 years old and somewhat over weight. I came to you about a year ago with my right hip giving me trouble. I stopped jogging and went to walking as an exercise. The hip stopped hurting but now transferred to my knee. I did physical therapy on my hip which helped my range of movement as there was a remarkable difference in the range of my right to my left. Would the 6 month shot stop this pain or do I need a knee replacement?
