Fasciculations can be caused by conditions such as benign fasciculation syndrome, stress, excessive excerise, electrolyte abnormalities, and can also be seen in other conditions. If you are having alot of neck pain, it may be reasonable to check an MRI of the cervical spine. Also, if these symptoms have progressed since you were evaluated by the neurologist it may be reasonable to have a repeat evaluation. If you were unhappy with the first neurologist, I would encourage you to seek another opinion (perhaps at an academic center). Good luck.
