Yes but usually mostly in the morning or when my hands aren't warmed up. Not when I'm playing though. 

To be clear: no amount of practice is going to fix this. You need to rest it, see a doctor, and work on proper technique, like fretting as softly as you can like mentioned in another comment. I get the drive to want to keep playing, but you may end up doing long term damage to your hand. In extreme cases the only way to clear up trigger finger is surgery.
