Red bottoms of feet,pain full burning why?

The bottoms of my mom's feet are red ,she says they feel like a hot burning pain at night? Why? She is not a diabetic and boes not have gout.

It could be babeciosis, a tick born infection that usually comes along with Lyme disease. One of the primary symptoms of babeciosis is burning in the feet.

If you live in the eastern United States that might something you could check into with your doctor.
