Shivering

This morning at work I was standing talking with someone and my arm started shaking so much it was like I was shivering in the cold. It's the first time that happened without any assignable cause.

I'm finding that if I'm cold, my right arm will shiver much more and much sooner than my left arm. If I'm exerting myself, it's the same sort of thing, but today was the first time my arm shook like that with no apparent cause.

New sensation

Had a "new sensation" last night.

Anyway, the sensation was actually a feeling of my arm being "normal". I could actually feel something like the waking up after your arm has been asleep (without the pins and needles feeling). Still today, my arm has that warm kind of feeling - even though the shaking is not gone.
