I'm wondering if anyone can relate or has any helpful info. For two years now I have been dealing with constant neck pain, pinched nerves in neck both sides, weakness in legs, was found to have small syrinx on mri at c6&7. Was given dx of Syringohydromyelia. Constant pain, fatigue, neck, shoulder pain and so on. I was told by neurologists and neuro surg that the syrinx was to small to be causing these symptoms. About 6 months ago developed severe shock like sensations associated with movement, sound, touch, changes in position. I have a few buldging discs but nothing impinges on the cord. I have severe ringing of the ears at night when i try to go to sleep. the shocks got so bad one time with dizziness and numbness in my face I was hospitalized for 4 days. Nothing has changed. Mri after Mri, ct scans, lumbar puncture, evoked potential test, sleep study, no explanation for these shocks that are actually called L'Hermitts sign and is one symptom of multiple sclerosis. Blood tests, still nothing. and they still say the syrinx is too small to be causing all these symptoms. They are ruling me out for Multiple sclerosis, but everything has been negative xcept the shocks/ L'hermitts sign. Now I am going to see this so called expert the best of the best of neurologists around. What is going on here? I am so frustrated, in so much constant pain, and these shocks are unbearable. Has anyone ever had these shocks? Oh and lately I have had severe headaches, and trouble swallowing and increased thigh heaviness and pain. Is this early signs of MS or is this the Syringohydromyelia? Please help with anything anyone may know or can suggest. Thank you. Desperately seeking a diagnosis.
