Had strange feeling in my heel for 5 months, what could it be?

5 months ago I was doing some high intensity treadmill running, after I finished I had no pain or nothing. Later that night I was heavily drinking right into the next morning. After waking up I had this pulsing/tingling feeling in the heel of my foot which I only really notice when laying or sitting down.

I’m 22 and have no health issues I’m aware of, never had these symptoms before. Any help would be greatly appreciated.
