Thanks doublevision - glad to know I'm not going crazy. I thought the sensation was quite 'cool' initially but it has now worn very thin. :-)
Hi Poppy, yes that's one of the many sensations I get from Lhermitte's. I get a similar buzzing in my quads as well as my feet, and the electric jolt down the spine. This was my first symptom. I had it for a few months in 2007, it remitted, returned a year later and I've had it ever since.
