My foot hurts but I didn't injure it.

Here is an example of a patient that had a painful red swoolen foot but didn't remember injuring it.  This was actually a person with diabetes and neuropathy who had a foot fracture with no pain.  That is also called Charcot foot.  If you have diabetes and don't remember an injury but it hurts ask your doctor if you have a Charcot injury.
To your health,
