Has anyone had a hiatal hernia?

I’ve been having heartburn for a week straight, nausea, chest pain radiating into my shoulders, neck, and head. I also have been having a “choking” feeling in my chest, so so sick I’m losing weight cause I just can’t eat but haven’t puked. (And no I’m not prego) FOR A WEEK STRAIGHT! Been to my Dr and she tried putting me on pills, which I tried didn’t work…then after a week still not gone so I tried to go back to my dr and she told me to go to the ER…blood, urine, and gall bladder all fine. Also drank some chalky stuff that makes your throat numb in the hospital and that didn’t take it away. I think it’s something wrong with my esophagus or a hernia…I’m in unbearable pain and discomfort and not one antacid or pill takes any of it away. ER said need to see a Gastroendologist and I’m waiting on a referral.
