“On and off chest pain suddenly?”

I have a history of overeating but I'm definitely not obese and my family overeats too but don't have these symptoms. I had a migraine for a month and a missed period for a month. Suddenly one night I had sharp chest pain that felt like a heart attack and I never had it before. I finally got my period that night, but horrible sharp chest pain. Now sometimes here and there I get dry coughs out of nowhere suddenly. I don't get sharp chest pain anymore, though, but my voice is definitely hoarse suddenly and I sometimes get acid in my throat. The ER never looked into my body exams but they just diagnosed me with GERD they never did a proper diagnosis other than a common chest x-ray and blood work.
