I am 29 Y male having burping, chest tightness, breathlessness, and neck pain for 3 weeks. After 4 days i took ecg. It was normal and only sinus tachycardia. I was taking pantaprazole twice a day but burping didnt go. After 6 days i stopped pantaprazole. Bp was normal always. Started taking voltapraz 20 for past 6 days as per doctor's advice. Burping is reduced a bit. But still after sleeping and waking chest tightnes and pain in left side and right. That too when i touch my ribs i feel more. And if i eat more i get breathlessness. I have vitamin d deficiency 9.7 . And when I climb more stairs I feel like my heart is pounding more. Is it normal? Or should I need to take any more tests?
