Handlebar Palsy

Sounds painful...but it is really just lame. I have been bothered by this for over a month now. I can't move my pinky and ring fingers as per the picture below

This article explains what is going on, and why I, like you, am a living example of how one can live with any kind of Palsy...hahahaha:

Handlebar palsy

Ulnar neuropathy, known to cyclists as handlebar palsy, is caused by compression of the ulnar nerve at the hand and wrist (Fig. 1). The ulnar nerve controls sensation in your ring and little finger and controls most of the muscular function of your hand. Compression of the ulnar nerve is a common problem for competitive and recreational cycle enthusiasts, alike. Compression is the result of direct pressure on the ulnar nerve from the grip on the handlebars. Often, the nerve may be stretched or hyperextended (extension beyond its normal limit) when a drop-down handlebar is held in the lower position. The pressure placed on the ulnar nerve results in numbness and tingling in the ring and little fingers or hand weakness, or a combination of both. Symptoms can take from several days to months to resolve, but surgical treatment is rarely necessary. Rest, stretching exercises, and anti-inflammatory medications, such as aspirin, usually help relieve the symptoms. Applying less pressure or weight to the handlebars and avoiding hyperextension can help to prevent a recurrence.

You can overcome or prevent overuse injuries altogether by making some adjustment to your equipment and behavior. Adjusting the handlebars, the seat, and the pedals to your fit is the key to preventing most overuse injuries. Adjust the bike so you sit in a more upright position, taking the weight and pressure off your hands and wrists. Take a rest during long rides and change your hand position on the handlebars often. Shift your weight from the center of your palms to the outside edge of your palms as often as possible. Wear padded gloves and add handlebar padding to your bike to help protect your hands from injury. The padding absorbs the shocks and jolts from the road, limiting the stress transmitted to your hands. Your hands will also be able to handle the stress from the roads much better if you complete a short session of hand and wrist stretches before hitting the road.

Most often, overuse injuries experienced by cyclists stem from a lack of specific preparation. With the proper training and equipment, you can minimize the risk of these hand injuries.
