Couple things. I know at your age that might seem devastating but honestly it's nothing at all in the grand scheme of what you could contract. It's really NOTHING! So you're lucky there. All those excess tests are only going to put you in more jeopardy, I'd totally avoid that. If you want to do some further research do it yourself online rather than ask a Dr what to do. We already know he's either gonna try get you to believe you have cancer, believe you need to take drugs the rest of your life, or believe you need an operation and or further testing. All unnecessary for such a minor issue. I'd honestly just move on, live and learn. Just do some of your own research. Tell him the same thing as you don't want him panicking either for no reason. Dear lord please comfort this couple and show them what to do. Amen.
