Ive been having a strange warm sensation in the lower right abdomen/pants belt area - sort of like a hot knife.  There isnt any pain really, but its enough of a sensation that I notice it throughout the day.  Its been going on since mid November and my primary care physician thought it might be some sort of an infection so I was given antibiotics - which I was allergic to (it was sulfur-based) and so stopped immediately - but since the pain went away he did not put me back on any antibiotics.  In the last two weeks the sensation seems to be growing and is more generalized now to an area about the size of a softball.  What could this be?
