I once passed out on a plane after taking some benadryl and a whole flight to Spain I had leaned on my bent wrist.

Couldn't do anything with my hand for a week, I was able to grab things after a week but had very little strength and struggled to turn a door know. If I held a shot glass, I needed my other hand or it would spill.

Slowly it got better and by a month I was back 100% or so. Doctor had told me to wait it out as I likely pinched a nerve and it had to heal.
