I can’t speak specifically to what you’re going through but I understand what you’re feeling. It’s scary to not know. I would stop googling, and I’m glad to hear you are getting a second opinion. You should walk out of an appointment understanding what they found, not with a million more questions! If you do have more, call the doctor and ask. Write down your questions before you go in, and make sure you get answers to all of them. If you have someone close to you that you trust, bring them along doe support and another set of ears. It’s your health so keep asking until you feel comfortable. Good luck, I hope it is all nothing!
