I would get checked out by a specialist, you have been suffering from GERD so it could be a bad case of Hiatus Hernia, most people with GERD have Hiatus Hernia where the fundus of the stomach can slide up and down through the diaphragm but in some cases a portion of the stomach can get trapped between the esophagus and the diaphram in the chest cavity in a permanent state, which can make you feel bruised.
It can also be acute Dyspepsia, which is brought on by GERD damaging the lower esophagus.
But again seen as though you have been diagnosed with gallstones i would still suspect that is the cause of the pain, whenever you eat the gall bladder becomes active, releasing bile to help break down the food, the pipe is basically blocked by small stones, so after you eat this causes inflammation and hence the pain, the pain will be in the upper abdomen, lower chest, but more to the right hand side.
The gallstones can be passed in time, if they are too big to be passed then you normally need to get them broken down to a passable size, but this will still be painfull, if you have lots of small stones then the this can require surgery to get the gall bladder removed.
the pain its after i eat any kind of food even though i been cutting down the fatty food i still get the pain
Call the Dr. and ask for a surgical referral.

Does the pain come after you have eaten fatty foods? If it is gall stones then an attack would normally be brought on by eating fatty foods as this would make your gall bladder active. Your doctor should prescribe you some very powerful painkillers, seen as though you have been diagnosed as having gall stones i would suspect that this would be the cause of the pain.
