One week ago, i started to feel a lot of gas in my stomach, and i had hard to burp them out. Sometimes i felt a little bit stomachache after i eat a lot, i guess this looks like gastric ulcer. Then my throat started to feel weird, i always feel something was inside of my throat and very sore feeling. After that, i had hard time breathing. It was like your diaphragm can not expand completely, and weird feeling around the lung area. I don't have cough or chest pain, i was wondering if it is pharyngitis. In addition, i have had pvc's and palpitation for about 2years, they come and go, i believe they are related to my stress, but i do not have any dizzy or any other symptoms related to cardiovascular diseases. However, when everything come together, i feel like i am so sick, and i couldn't do any intense exercises because i cannot catch my breath. I did research online, and i notice that Prilosec very beneficial to the acid in the stomach, but it might trigger more pvcs. Any one can help me with these problems? Or anyone else now suffering the same thing like me? Oh, and due to my allergy, i have running nose, that is another reason i can not breath.
