Yes, you need a Podiatrist. If you are on Medicare, it will pay for you to go every 10 weeks. You just need to make sure they take Medicare.

You should speak with your primary physician to get a recommendation or use the search engine on your computer to check local podiatrists, their costs and their coverages.
