In the middle ofthe night last night, two different occasions I felt like I had been shocked by electricity and my ledt arm went numb, but yet hurt pretty badly. This has occured before. I wasnt worried before, because when I get overly tired, I will talk and sometimes walk in my sleep. In fact, the things I do and say are pretty wierd. So last night I thought I was being shocked by my electric blanket - so once theelingcame back into my arm, I removed my electric blanket. Juzt trying to figure out what this sbocking, numbness is.
