I have met two padeatricians already but all are prescribing the same medicines but my concern is  to get a permanent solution for this. None of the doctors are telling what is the problem or disease is. And the cause....i need a doctor who help us on this and give a genuine treatment and permanent solution to this .. as a parent iam very anxious as my little daughter is also having leakge in heart and murmuring also i am ready to meet the doctors who can guide us on this.
