Talk to Gastroenterologist on Stomach And Chest Pain

I will start from the beginning 2 years back in 2018 after my emergency c section I was diagnosed with acid reflux and had to take pantoprazole and zantac and also another medicine to regulate my stool and air in my stomach now ever since I did the course I started having severe chest pain. My doctor said that its because I am depressed and it will go away but it's been 2 years now and I still have the chest pain. I am still always very dizzy when I wake up to when I go to sleep I am dizzy and it feels like I might just collapse. I have gotten countless of tests done to see if something is wrong but they say everything is normal. I even got all of my heart tests done and it's all normal but now i am feeling the same thing. My doctor again gave me pantoprazole and I took one and right away it gave me chest pain. I am having the same symptoms dizziness chest pain. And my stomach is very hard and I have hard time going to the bathroom. Can you please help me out. Thank you
