Hi, thanks for writing to HCM.
I suspect that you could have developed secondary degenerative arthritic changes (wear and tear in the cartilage
) in your right hip joint which is causing you pain as well as difficulty in walking with losing balance.
An xray of the involved knee joint will show up the amount of arthritic changes in the joint.
Treatment of the condition depends upon the severity of damage in the articular surfaces. Physiotherapy
in the form of strengthening of muscles will be of some help but not curative for the condition.
I suggest you to consult an orthopedic surgeon for further management.
Hope this information is helpful. Good day
