hello my name is kala i am 21 years old and i just had a baby 3 months ago and ever since then about twice a month i have a very sharp constant pain in my upper abdomen just below my rib cage and the pain goes into my back. and from this it causes me to have nausea and then vomit, ill have the pain all day until i vomit and i start sweating but feel cold, i only get this way if i eat something greasy. is this a case of gallbladder disease and does this mean i have to have surgery
