Look on the pediatric cardiology forum I think you will find input there ..Good Luck
I think we have to be our children's advocate. If your mama warning bells are sounding, act on them. That is my firm belief. I'd call your primary care doctor and say that you feel something is wrong and would like a second opinion---- who do they recommend you see? If those pains increase, then I'd go to the ER, yes. How awful to have something unthinkable happen while being poo poo'ed by your doctor. So, make some calls and get a plan together. Second opinions are valuable---- they help you either have faith in your doctor or lose faith. Good to know when it comes to the health of your beloved cherub. good luck
I agree 100% with specialmom! As a mother and a congenital heart patient, I have learned to always trust my gut... If you don't like/trust the answer you get at one hospital/doctor go to another one. Good luck!
