Sounds like nerve: Have your doctor evaluate for possible tarsal tunnel syndrome or peripheral neuropathy. Several potential causes. Maybe, get neurology consult.

Possible neuropathy: Neuropathy can happen as a result of trauma, or nerve damage due to the consumption of alcohol or certain medications. Symptoms can range from a numbness and tingling sensation, possibly a burning sensation, to an uncomfortable painful sensation of the extremities. Get evaluated by a professional to determine the exact cause in order to get the appropriate treatment.
