I am 19 years old. Before one and half month, one day after lunch my heart is beating faster and it is calm down by itself and again at 4 am when I was sleeping I feel the same and I got some burning sensations at stomach and chest. I went to the doctor near me and they said it was gastric trouble he gave me rabisor tablets .but I did not feel better again I go to another doctor he gave me nexpro 40. It is better but if I eat any thing little spicy again I am getting the same .these time I go to another doctor he gave me pantop dsr .is it okay to use pantop after using the other tablets or what you can suggest.
