<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have what i call attacks in my upper abdomen. They usually last an hour or two and have nauseau vomitting and cold sweats with them and are very painful! Last night i has the worst one ever! They are becoming more and more frequent like every night. Last night i was in tears the pain was unbearable and was going all the way to my back into the right part of my chest. It still hurts today but nothing compared to last night. I have an appt in two weeks but i dont know if i can take the pain that long. Is this something i would need to go ahead at go to an ER for?  <response>: Hi. Thanks for your query. The most probable cause of the pain you have explained are :-Gastric ulcer as you pain is periodic and in upper abdomen--Pancreatitis. -Gall bladder infection and or stones. I would advise you the following :Go to an ER. This is because you will get all the tests of blood, urine, ultrasonography, X-ray abdomen in the standing position and if needed a CT scan. This will enable us to get diagnosis and then a perfect treatment can be planned.
