2004 Dodge Ram Won't turn left

I took off from a stop, making a right turn. When I turned the wheel back to straighten it up it had some resistance. I then wiggled the wheel back and forth as I was driving, no issues except there it was a little titer. I went around a corner same thing, when straitening up the wheel, resistance. When I stop to turn on to my road, I couldn't turn the wheel left at all. I had to go up the road and turn right in to a lot. Sitting in the lot I tried to turn the steering wheel left it wouldn't move but it would move to the right. I got out looked under the hood and the truck nothing looked out of the norm. After I got back in the truck I could turn the wheel to the left.
