Lori,
Most of us understand the stress and anxiety of having to wait for our tests, it can be excruciating at times.
When our doctors schedule our appointments what is "only" a week to them is like Kasey said, six months to us.
Let your doctor know how high your anxiety level is getting, it's my understanding if your doctor happens to work at the facility you will have your tests at, he can speed up both the test and the length of time you have to wait for the results but a doctor ordering from his office to another facility waits longer. That's just been my experience, my doctor does not work in the hospital where my tests are done so I'm a waiter at test time.
I wish you the best and hope you can get in there earlier.
Kathy
