Gallbladder is painful

Last August I had every classic sign of a heart attack and after seeing the Dr's, I told one that I had the feeling of someone shoving their knuckle in my back just under the right shoulder. He said it sounded like the Gallbladder and sent me for a Ultrasound. The test came back normal with the exception that the Gallbladder walls were thickened (3). My family Dr. thought it should be removed but the surgeon feels only walls 5-7 should be removed. So I have lived with it. Now here it is January 09 and the pain is much worse, pain in the back, under my right rib cage and even a burning sensation every now and then. I told the Dr. if taking the Gallbladder out will stop the pain, then take it out. Also, I have a tremendous amount of pain in the upper stomach after eating fatty foods. Well I went for another ultrasound yesterday and the specialist said the walls were still 3 but I haven't heard any official results yet. Has anyone else had this or simular? If so, will or should the Gallbladder be taken out? It's really a pain in the.....Back and side. Thanks for reading.
