For the last 1.5 yrs having trouble with unsteady balance. Symptoms: unsteady drifting to right; unable to walk stairs, inclines & trouble getting out of vehicles (change in planes causes unsteadiness); tingle in outer thighs; when episodes start -- have blurry vision in right eye and then difficulty keeping right eye open; sharp pain in back of head when bending over; can happen daily to several times weekly. Tests completed: Vit B lab, MRI & MRA of head, audiologist, ENT, cardio -- all negative. Neurologist ruled out diabetic neuropathy (not same type of symptoms & ruled out MS (no lesions on MRI, spinal tap from 2002 negative). EMG revealed: mild axonal polyneuropathy with no denervation & MRI spine revealed: left lateral/neural foraminal herniations L2-3, L3-4 & L4-5. Have seen several drs -- no diagnosis. Unable to work due to safety of falling. Need help so I can return to work. Any suggestions?
