Thank you posting your query on ATD.
In a person your age, tendonitis is very common, and it could be the reason you are experiencing pain.
For this, you will have to see a doctor to examine your knees.
Doctor may suggest MRI of the joint to assess whether there are any torn ligaments, tear in meniscus, inflammation of tendons or the development of arthritis.
heat therapy may help you.
The more exercise the knee joint, the more you will be able to prevent pain.
You may use a knee brace while walking.
Hope this is helpful!
