Family Heart Conditions?

Paxten had strep throat about a month ago and woke up Wednesday morning saying his throat hurt. He didn't really eat good Wednesday morning but I gave him a ice pop to cool his throat, I thought maybe it was just dry because he sleeps with his mouth open and snores, in about an hour he seemed to be fine and ate a big lunch. He played all day yesterday and never ran any kind of fever. This morning he woke up crying his throat hurt and I looked in his mouth and his tonsils were so swollen they were both touching the ulva thingy in the back of his throat. I gave him a glass of water but he gagged on it and couldn't swallow it but still no fever. I called the doctor and got him in today. Well he has strep again, they did swab him, but they asked how long he has had a heart murmur. He hasn't. She wanted him back in 2 or 3 weeks to recheck it. She is hoping that maybe his body is just under stress from the strep. We are praying that there is no murmur when we go back.
His chin looks good and is healing well.

Is there any family history of heart issues? The doctor asked and I told her that I would ask you.
I have tried texting through email your number, the other number you gave me and the phone you texted on the other night but they don't look like they are going through. They send but I get a message back saying they didn't. Must be something with my email but I am not computer smart enough to figure it out. So please let me know you read this blog post. You can either comment here or text. If you text I will let you know on this blog that I got it.
