Driver side tail light and license plate light

I have a 05 dodge and this morning I noticed that one license plate light was flickering. So me beinging me started messing with it and noticed that the bulb is kinda loose so I pulled it out and used my knife to see if I could push the prongs closer so it would be tight. Well in this process i hit something in there and the driver side tail running light shut off and the other license plate light shut off. Ok so I checked the fuse box and there was one that blew. It was a 20 amp fuse and I put a new one in but still no light. The stop light and blinker works and the passager side tail light everything works. Anyone have a idea???????
