I'm sorry to hear that you are is such discomfort....
It sounds that you are best to go to ER ....
Pancreatitis could be a cause >> abdominal pain/ lower chest pain/ back pain / nausea and vomiting ...So this is one very possible diagnosis but not the only possibility...
Acute pancreatis is a medical emergency and needs immediate evaluation
( In worst cases it can lead to fatal complications )
So you really need to get to ER and not put this off!!
Other potential causes could be acute cholecystitis ( gallbladder infection) gallstones ....
Other conditions possible but the ones I have listed above I think more fit ..
Please get to ER and not by driving yourself!
I hope that this information is helpful for you Let me know if I may be of further help !
If you have further questions or concerns I will be happy to get back with you
If my answers have been helpful and to your satisfaction then please remember to leave positive feedback Thank you and Best Regards,
