When school's off for more than three or four days, I usually don't write much (I prefer to type at home!) and so when I come back and hold my pen[cil], my fingers refuse to move like they normally do. My handwriting comes out all weird and I have to really make an effort to write something for the first few hours.
My question is, is there a word for this, except for maybe 'being out of practice'?
You can say "After a few days I seem to have got rusty fingers".
rusty (adj)
"stiff with or as if with rust" - Merriam-Webster
"weakened or impaired by neglect, disuse, or lack of practice" - TFD
If you use the phrase "penmanship atrophy" I'm sure you'll be understood. In fact, in the 21st century, there is epidemic cultural penmanship atrophy. (Put that in your pipe and smoke it.)
Numbness of the thumb, index, middle/ring finger.
Sounds quite a bit like agraphia:
Agraphia is an acquired neurological disorder causing a loss in the ability to communicate through writing, either due to some form of motor dysfunction or an inability to spell.
