I am having discomfortness in left side head,left side hand and left leg. Discomfortness more in hand and leg. I am also having gas troubles also. Before 5 months i had done ECG for chest pain and ECG were normal. To rule out heart condition or blockage i had also done TMT which were all okay and normal. Still i have sometimes diacomfortnesa in left leg and left hand. Is this symptoms are a cause for alaram. Does this still have a connection with heart if ECG and TMT were normal. Please guide me, so that i can be slight calm if it is not linked to heart. Doctors also say that gastritis also cause left side body discomfortness.
