Nobody knows your body the way that you do, especially not the Dr's, you know when it feels good and when it feels bad, and you know when something inside of you isn't right. Just because the Dr's aren't able to give you a proper diagnosis doesn't mean there's nothing wrong, just means they haven't found it yet. Dr's only know what you tell them so be very, very specific about
your symptoms and the pain it's causing you. Also, do your own research and don't be afraid to say to the Dr, "could it be this?". They don't know everything, that's not possible. Let the Dr. know just how concerned you are, it's your body and your health you're dealing with. I know it's difficult cuz you don't want to be labeled as a hypochondriac or a cry baby, I worry about
that all the time too. Just remember, you are the best judge about
what's going on in your body, and you know that you are ill. Please hang in there and stay positive, don't worry about
the upcoming tests, you'll get thru them just fine. My thoughts are with you. Please take care!
