Chronic pain and upper abdomen? Please see added messages!!!

I have had severe lower chest pain and high stomach pain with some nausea and vomiting for and entire year. Also severe indigestion that is treated daily with a prescription dose of Nexium and Famatodine twice a day. Since the age of 19 I have multiple medical issues. I am now 43 year old female.. I have Wolf Parkinson White syndrome with an ablated AV Node. Two pacemaker placements with one wire revision the last being in Aug 2023. In the past 20 years I have had a C-section, hysterectomy, gallbladder appendectomy, a open surgery to the right abdomen for a repair of my urethra due to over 100 are more kidney stones in 15 years. I have been experiencing symptoms of uncontrolled pain for a year now I have seen every specialist they can think of. I have had many test to include but not only a colonoscopy and an upper stomach scope. With no answers I am very fortunate to live in the town of Augusta Ga. With one of the states large Medical colleges and research hospitals! Unfortunately the Drs are now talking about UNC but I just don’t know what to do!
