Hey Blake. Welcome to the forum.
The MRI was probably ordered as diagnostic investigation of exclusion.
GBS dx usually involves a clinical examination by a neuro, spinal tap
and nerve conduction studies and EMG (as you mentioned you're having)
Do you have progressive fatigue & deep muscular pain going from your legs up to the rest of your body?
Do you have any diminished sensory perception regarding position and
impaired reflexes?
These are common with GBS
Please keep us posted and best wishes!
Niko
Thanks for the response !! No I do not have any muscle pain and my symptoms are episodic and not constant . I am concerned I might have the cardiac variant of gbs I have heart arrhythmia and orthostatic hypotension but that too seems to be episodic but I don't have excersize intolerance or trouble going to the bathroom
And wouldn't the mri have shown lesions on the myelin sheathe that would have been picked up by the MRI?
