Here is My Question:
I have been getting brain MRI for 2 years. My symptoms are buzzing sensations in my left leg and pins and needles in my left foot every now and then. My vision got blurry so I've seen the eye specialist multiple times but he said my eyes are perfect.
Clinical History: Intermittent buzzing left upper limb and lower limb
(independently). Brisk knee jerk. Otherwise normal examination. For exclusion
Cranial MRI results:
There is no cerebral mass lesion identified. No cerebral cortical signal abnormality identified. There are several foci of high signal intensity again seen within the cerebral white matter. There has been no increase in number when compared with the previous MRI dated 11/11/2017. There are no specific
features. There is no lesion within the corpus callosum. Cerebral deep grey nuclei are unremarkable. No focus of cerebral diffusion restriction is seen. No surface collection is seen over the cerebral convexity. No lesion seen within the brainstem or cerebellum. No hydrocephalus. Intracranial arterial and cerebral venous sinus flow voids are unremarkable.
So my question is my neurologist said my brain MRI is fine and he doesn't think I have MS but has now booked me in for a lumber puncture. I don’t know what to do I’m so scared of getting a lumbar puncture should I go ahead even though my MRI is fine ? Please help :)
Lumbar punctures are safe and well tolerated as long as there is no mass lesion in the brain, no blockage in the spine and when done using either an atraumatic needle (no bigger than 22 gauge) or a small bore (25 gauge) regular needle.
It sounds as though you are the perfect candidate for a lumbar puncture based on the history you provided. As long as the procedure is done with the type of needles described above, there is a very low risk of headache after the procedure and little discomfort during the procedure.
