Red Yeast rice works like statins. It contains statin-like chemicals, and we know statins can cause PN. Each of these supplements varies in how much statin-like actions are present, depending on the quality of extract used by each manufacturer.

Riding bicycles move the ankle alot. If you have any tarsal tunnel entrapement issues or arthritis, you can aggravate the nerves with this form of exercise. I have scar tissue from a surgery on my left instep, and the bikes always aggravated pain in that foot for me.

Your foot burning can be due to many things, in other words.
