<human>: Give me the gist of the text in a nutshell

Alright, so I went to the gym tonight and did some lifting for the first time in a couple months. I didn't feel as though i over did myself, and i wasn't doing anything crazy/stupid with the weights or machines. The whole time at the gym my wrist felt fine. Never gave me any problems or anything. Never felt a tear or heard a pop, or any of that. It even felt fine on the way home. But, after I pulled in my driveway, I noticed it started to hurt a little. Then after about 15 - 20 minutes of being home, it just really started to hurt when I put ANY amount of pressure on it. Now its basically useless, I can barely do anything with my left hand without it hurting. So what the hell? What happened during the 15 minute drive home from the gym? Is it just from over use, too soon? Im sure this has probably happened to plenty of people before. I just honestly don't understand what happened.
<bot>: Went to the gym, worked out. Everything was fine. Drove home, wrist starting hurting. Now can't put any pressure on it what-so-ever.
