I am 27 years old guy , i hav been feeling bowel sounds in my chest since 3 years ago in 2011, (at time of firing up some war in my country), with no other clear symptoms, in 2012, i started feeling interrupted GI gases and chest bowel sound then frequently heartburn for whole one year . in June/2013 at one day after good lunch i got clear palpitation and feeling like irregular heart beats, at the night palpitation became too stronger as i could count them directly by my ears while my head on pillow ( heart beats around 100 beats / min) and chest pain with shortness of breathe . next day i had ECG and blood pressure tests which were perfectly normal 120/82 , but the heart beats 98/min the doctor suspected anxiety because i participated in the war before 18 months. palpitation, increased heartbeats, interrupted gases, heartburn, reflux and bowel sounds in a chest are still existing untill now, i had ecko in last Sep and my doc noticed some weakness in left side of the heart and suspected that its related to myocarditis and advised me to not do strenuous works for next three months and does not need treatment, sometimes i realize palpitation is related to GI problems because it worsens when i hav constipation. im not sure if all that are dangerous or not, im trying to play football with friends but always feel strong palpitation and stop for 5mins and play back for 10 min then stop again when i feel its strong palpitation ,some times i do my favorite sport spearfishing under water free diving but im scared to challenge and inforce holding breathe like 5 years before, all the time im choosing to stop in competitions i do, scarring of heart attack or some thing .
