I am 18 years and doctors have identified gallstones. I have pain in the abdomen rises and, as at the back. I have plugged more pain after using the toilet and felt a little bit. I still feel after the heartburn pain is releaved.
I wanted to ask, weather
a) Symptoms of gallstones and ulcers are the same?
b) no connection with the acid, gallstones and constipation, black with the chair?
c) Is there another way to gallstones without undergoing surgery to remove a natural medicine and the like.
