Oh my goodness, I know how this is! I went to the ER at three in the morning a few months ago, with sever, severe pain in my abdomen (it had started smaller and my doctor dismissed it and said it couldn't be WHAT IT WAS). I had pancreatitis. He sent me home with pain meds and then we later find out my levels were much to high, I should have been admitted to the hospital. :/ Also that my lymph nodes were really swollen.

So I know how you feel. D: I'm so sorry. I hope all gets better!
