Could be RSI (Repetitive Strain Injury). I had that after binge coding for an extended amount of days without doing anything else. My right forearm was perpetually contracted and hand was prohibitively stiff.

Went to a massage therapist who massaged my trapezoids, some spots in my back and finally my forearm. After 2 sessions over 3 days, it was gone. But I didn't code during that time.

Side note: pretty sure I got much more programming done during my time off the computer than on.
