For Several Weeks My Left Heel Has Been Very Tender.

For several weeks my left heel has been very tender. No amount of massage or resting has helped. I've had no injury, however did hurt my back/left hip while moving our household early December. While my back and hip are finally better, my heel on the same leg now feels so tender I cannot put my full weight on it while walking. It is not my entire heal, just the back 1" or so.
