I too have had a buzzing sensation but mine is in my left foot . Have had it for 8 months now and have litterally went to every Doctor, Neurologist 3 foot Doc and reg internist. Have had mri, xrays nerve conduction muscle testing blood test etc etc etc. All came back somewhat normal except a disc problem in low spine and spinal stenosis. I notice the symptons more when I am tired or stressed. Doctor put me on all different meds none helped made matters worst. I am now seeing a kinseologist chiropractor and then has helped until recently. Just had a accident and fell on my knee, vibration is really bad now. Sorry to go on and on. Feel free to write. Ellice
