I was diagnosed with a sprain in the ligaments around my tarsal bones, what is the best treatment?

RICE: Rest, ice, compression, elevation.

It depends: Most mid foot sprains can be treated with ri ce, rest/ice/compression/elevation, as previously recommended. I do want you to be aware that there is a much more significant injury that can occur referred to as a lis franc sprain. This would be felt more on the medial (inner) aspect of the mid foot. It requires more intensive treatment ; at a minimum immobilization and in some cases surgery.
