So tired of doctor appointments

I am a little discouraged after my doctor's visit today. During my last CT scan they found a Hemangioma on my L2 vertebrae. A hemangioma is a benign bone lesion. I have an appointment with a new doctor tomorrow morning to discuss if anything needs to be done about it. Usually they leave them alone, unless it is causing symptoms. Because I am having some numbness in my back and legs they want me to talk with this doctor.
On the endocrine front we have ruled out several things, but they need one more test to completely rule out Cushings. Two have come back negative. If I do not have Cushings - they will not surgically remove the tumor on the adrenal gland but will check it in one year to see if it has grown. She is having me take another test to conclusively determine if I have diabetes. Right now all she can say is that I have impaired glucose tolerance. I will take that test Friday. If I have diabetes, she will send me to the diabetes center here in town for education and we will discuss medication. She is also running a test having to do with growth hormone. I have lost 8 pounds and my blood pressure is still down.
I am finding it hard to continue to wait for more tests...a lesson in patience and trust.
