Why does my back still hurt? 2 years post lipoma removal.

About two years ago I had a lipoma removed from my upper back. At the time I had it removed it did not hurt .now lately I have a pain in the same exact spot and it radiates down my back and wraps around to the front . When I went to my regular doctor the other day he told me it has nothing to do with the lipoma ,just has to do with aches and pains of getting old I am 52! Pain feels like a Charlie horse or a bad cramp and is constant .
