I do have hypertension for which I take 4 meds for. There is not any one thing I can determine that sets off an attack. It comes when it comes. Yesterday I was doing the education portion of a new job and had to quit because the pain was so intense I couldn't concentrate. I do not have, at this time, periods of diahhrea or constipation. I have been told by my doctor that I have some irritation to my stomach lininand a small hietal hernia. The pain is in the epigastric region directly below my sternum and will radiate to my back. The pain in my back will be in my upper back. My doctor has no answers and says that test are being done for 4 or 5 new meds but until then there is nothing he can do or recommend. I have suffered with this pain for 3 years now and it hurts like ----!! What is weird is I used to drink ice water and that would make it quit, usually. Also if I could throw up, not because I was nauseated, but just the action of the muscles when you throw up seem to be the reason it would stop. However, the episodes are becoming more frequent and nothing seems to help with quick results anymore. I have come to the point that I would participate in any ,medical trial that shows some hope. I have had 3 colonoscopes and 2 broncoscopes an ultrasound and an MRCP and it shows nothing.
