Unfortunately we can't give you usable answers. You will have to get your doctors advice.
Because of your age, and relative expectation of multiple age related health issues, you need specific guidance to prevent further problems.
However, barring any contraindications, the typical recommendations are NSAIDS such as naproxen. Diet will also help some.
If it's Rheumatoid arthritis, that will be a little harder to work with.
Your Dr. might also prescribe some steroids, if appropriate for your health.
Unless your DR. says otherwise, I would not suggest ice. Due to your age, your circulation is probably already somewhat reduced.
thank you for your reply. I have taken your advice and have made an appointment with my doctor.
