Tingling pinky and ring finger are almost always neuropathy of the ulnar nerve in the Guyon canal of the wrist due to pressure of the bars and road vibration.
I have not felt my fingers in almost a decade and in my case, the ulnar nerve entrapment is elsewhere. The entrapment can occur at the elbow, shoulder or cervical spine for instance but almost always the problem is at the wrist.
The tingling feeling usually takes several months to go away, OP should be fine in time. Nerves heal very slowly.
