I am 19 years old and I have been experiencing shocking bursts of numbness in my left leg. The numbness suddenly and unexpectedly hits my leg like an electrical shock, from hip to toes. It is so sudden, most of the time it is accompanied by panic and terror, for I lose all feeling in my leg: It does not feel like I have a leg at all when this happens. Sometimes my only my left foot goes numb: a dull aching numbness.
Originally, this would happen once or twice in a week. however, it has become more frequent. It now happens several times a day and the numbness or "shock" lasts longer...for 15 to 20 seconds.
I have also started to experience numbness in my left arm, from the shoulder to the tips of my fingers. Unlike the numbness in my leg, it starts out as a dull progressive numbness and spreads throughout. My arm feels heavy and my fingertips are cold.
At times, I will be eating something and it will suddenly start tasting like a chemical (almost like the taste of a cleaning product or the such. I've never tasted cleaning products but i imagine they taste that way).
