What's with your right hand?
Don't know. All my extremities ache a bit, nothing too unusual there. But my right hand now barely functions in some ways. Can't close or open a tap or a lock, can barely open a door. Can type a bit, but not if my hand needs to spread too much. Thumb and index finger are the worst. Pain radiates to elbow and shoulder. But it does not feel at all like an RSI. Nor does it feel like my hands were five years ago. Finer motor skills still go reasonably well. I could knit (because I taught myself to do it the German/Scandinavian way), draw, and write a bit two days ago. But lifting a cup of tea is nearly impossible.
Understaffed at GP because of holidays. But, they'll see me tomorrow. When the assistant heard my problem, she backed of telling how little space they had and said I really needed to come.
About a month ago I did snap my thumb backwards with a heavy bag falling and me just catching it. Maybe this is a delayed reaction on that.
Hope it is not something like a tear in a bone or sinew. Since today the thumb and index finger do look a little bit swollen too.
