Had tarsal tunnel release 10 mo. Ago, all of a sudden having ankle pain which is leading to some heal pain. Could this be a reocurrance?

Tough to say. Without an exam. It certainly could be, but an EMG, which I suspect you had in the past with your history, would be able to be compared with the previous and your answer would be forthcoming.
Possible. an emg/ncv comparison may be useful.
