If all they are going to do is give meds to cover up what is going on, what is the point? I am so frustrated with all of the "I don't knows" from the neurologist. I have this test scheduled for mid February. They already know I have nerve damage and orthostatic hypotension. They can only offer pain relief. With my ANA at 1:640/ speckled and positive small nerve fiber and orthostatic hypotension. The rest of my labs are normal. What would the benefit be for me to get this test. The problems are obvious, dysregulated body temp, heart palps, yawning episodes, dizziness, disorientation, sensory problems...... They will find the issues, but is there any way this test can help with determining cause?
