Migrating pain in right abdomen.

Hi, I'm 41, 102 kgs, 5.8", very active individual In may this year I started to have right side mild pain. It was mostly in right lower side of abdomen and sometimes felt in groin area. No other complications what so ever. In practo when I consulted it was termed as GERD and was prescribed Pan L in the morning and Pan 40 in the evening. Now for past 10 days same pain started again. No other complications...no vomiting, chills, fever, diarrhoea, constipation, aches and pains nothing. urine also crystal clear. For two days now a very mild pain is coming and going every where in my abdomen. Near naval, left side right side, upper, lower and everywhere for brief intervals and small areas. Today while I was having lunch a sharp pain started in love handle area and in two minutes travelled till my upper side buttock and vanished completely. Now, after normal passing gas and burping... everything seems to be normal. Should be worried? Should I take some medicines? Please advise. Thank you.
