Treatment depends on the cause of the murmur. Innocent murmurs
need no treatment and the child can lead a normal active life. Congenital heart disease
often requires major cardiac surgery
NO, only a licensed physician can treat the heart murmers.
I will advise not to try anything from websites, let your physician do the job, and when you are alright you will lead a normal, so wait for a couple days, you have full life in front of you.
