Electric Sensation Mary Electric Shock Sensation On The Left Side Of My Mouth?

Electric shock sensation on the left side of my mouth? - electric sensation mary

Ok, I know it sounds very strange, but sometimes I have this feeling of shock in the whole region is on the left side of my mouth! It started last year. I started very slowly and is getting worse. I understand every 2 / 3 months and lasts about 6 weeks or more! I'm not sure how to explain it, is like a cramp, mixed together, like an electric shock ... I visited my dentist, and was at St. Thomas Hospital in London, and nobody seems to know what is behind. It was just interested if anyone had the same problem as me.?
