MND, you be like Steven Hawking in a couple of weeks. Sell your bikes, quick!!
Lay off the caffiene for a bit?
Low potassium?
Try eating a banana or drinking some tonic water.
Parkinsons?
I get this occasionaly and only have one coffee per day and eat plenty of bananas, hasn't happened for a while so not parkinsons.
It just comes and goes, no idea why...
I get it quite often inside my thigh - whatever muscle that is - when I'm in bed
No idea what causes it
Can be a sign of muscle failure. Have you been practicing the five knuckle shuffle a bit much?
Possession. Is it your left arm?

Noticed any weakness in your limbs ? Fumbling buttons? Not quite able to tighten nuts by hand properly any more ? Any speech slurring (without beer) ? Or have you been coughing on your pringles.
