Recently got married, and my routine has been disturbed. Eventually it is taking time to get normalize.. But having few issues like burping a lot, and experiencing the pain in central lining of stomach.. i generally eat less and keep space.. but now i think food intake increased due to which the pressure is building up on the lining and making it pain.. so i am not sure about it exact cause.. this pain is from 4-5 days.. sometimes it fades away but sometimes it persist.. Recently had mouth ulcers..
