@50surgeries - Samantha, I can understand your fear and anxiety about your upcoming appointment. with your surgeon. I think that we all have a tendency to think of the worse possible diagnosis when dealing with any complications and pain, especially the unbearable pain as you have mentioned.

I always get jittery for even before a routine doctor visit. My friends say that I am crazy because I had a successful organ transplant surgery 9 years ago. Even when I'm feeling great, there is always a "What if?" in back of my mind.
You are the age of my younger son, and I want to tell you what I would tell him if he were facing a similar situation. Remember that you will be in good hands at Mayo Clinic. And it sounds like you already have a healthy relationship with the medical experts there due to your history. Try to think about good outcomes and feeling better. It is okay to be frightened and apprehensive, and it is okay to fear the possible outcomes, but I pray that you do get a favorable answer.
Samantha, How long have you been experiencing this pain? How do you feel in general?
