This is a very tricky situation to handle. The needle has bruised one of the muscles causing the trismus. There is no solid single treatment for this.
Most therapies combine taking muscle relaxants, controlled cold and hot compresses of the TMJ, and local application of a muscle relaxant gel over the joint.
I suggest you see your dentist or an oral surgeon for this management. Doing all or some of this will surely give you a better and faster result than doing nothing.
