[|Human|] I was diagnosed with Multiple Sclerosis in September 2007, and since then, I have been having numbness in my left leg sporadicly like an electric shock . It started to happen only when I tilted my head to the right and down toward my shoulder , but now, it can happen ANYTIME ... even while I am sleeping. While walking, this electric spasm halts my walking, as I cannot feel my leg and this sensation is overwhelming. My neurologist has gotten a recent MRI, but no results other than don t tilt your head that way . Please try to explain what I m feeling.
[|AI|]  Thanks for posting this query in ChatDoctorThis types of symptoms are common in patients with multiple sclerosisThis is mainly because of dysfunction of posterior column in the spinal cord. This may aggravate with change of posture and may happen spontaneously MRI may be normal years after the acute attackMedicines that may help are Gabapentin and pregabalinePlease visit a medical university hospital and get examined to resolve this issue Hope this helps
