Definitely overdid it…
I haven’t had full range of motion in my wrist due to tweaking it somehow awhile back…it has been about 3 months since I could do barbell curls…and if I turned the wrist to much in one direction-it hurt all over again…went to the dr. about it and was told that it would take time to heal but should be fine and I could still lift weights..so I have been able to pretty much do most exercises, and over time it has s l o w l y gotten better…
These past couple months I have still been able to do db bicep curls, but not with the same amount of weight as I used to..the wrist would act up if I tried to go too heavy…and I would "test" the wrist weekly as I attempted barbell curls but every week would come to the same conclusion: NOPE, not happenin!..the wrist would hurt like I was injuring it all over again…so I’d put the barbell back in frustration wondering when and if I would ever be able to do my barbell curls again :(…
Because of the limited range of motion my bicep workouts have pretty much just been doing db drop sets to failure on the day I work my back at the end of the workout…I felt like my biceps were getting a good workout doing the back exercises so I didn’t worry about them too much…but then I started to notice that my bicep vein I was so proud of had stopped popping out…and that was something I was so glad to see developing back when I started out..it was a real sign of progress to me…so I’ve just been waiting for my wrist to heal so I could get that vein popping again!!
So this week I didn’t do any extra bicep work after my back workout, and even gave them a few days to recover before working them on their own yesterday hoping to get them progressing again…well, not totally on their own, I also did legs yesterday…and as usual, I attempted a bb curl with a 25lb and…what?…no pain?…not even a little twinge of wrist pain?…get out!…no way, I must be dreaming this…yep, the wrist was ok to do bb curls again!!! FINALLY!! yay..that made me so happy 
It made me so happy that I overdid it…I alternated between leg/bicep sets and everything was going good…I did bb curls, standing cable curls, and bicep isolation db curls…by the time I got to the db isolation curls, I had already done enough and I should have stopped…as I was finishing up and doing drop sets to failure, I noticed that instead of feeling the burn, I wasn’t feeling much at all..by the time I got down to 6lb db’s I felt like there was no muscle in my bicep, the exercise didn’t burn as it usually did and I didn’t feel any pump in it at all…when I got home I checked out my biceps, no usual pump from the workout and they looked smaller… 
*Sigh* Oh well, another lesson in my fitness journey : the importance of knowing when to stop!

Sounds like you either strained or sprained the ligaments in your wrist. Next time you do it, wrap the wrist with an ace bandage when you lift. Lift lighter than normal, but it should still allow you to work at least a little bit through the injury.
Sometimes overdoing it is just right. Sometimes.

I had something similar with my wrist from of all things, bowling. It got so bad that just by slightly moving my wrist it would feel like it popped out of place, and I had no strength at all.
I ended up going to a chiropractor, and two visits had it staying in place. But I now wear a wrist guard when lifting AND bowling.

Oh yeah I bowled a few weeks ago and that KILLED my arm…I thought about quitting the game but the guy I bowled with was talking trash about winning so I was feelin too competitive to do that…hmm…guess i need a wrist guard for that too now!
