If you play video games and your hands start to hurt, you run the risk of suffering a repetitive stress injury that causes pain and even numbness in your hands. These symptoms are caused by swelling and compression along the carpal tunnel, a sheath for a nerve and some tendons that run from the palm to the shoulder.
Impingement of the ulnar nerve causes a radiating pain or numbness in the pinky finger, ring finger, and edge of the hand. This is called ulnar neuropathy, which can be caused by two different conditions known as cubital tunnel syndrome and ulnar tunnel syndrome.
The ulnar nerve is one of the major nerves of the upper extremity. Nerves are structures that allow information to travel from the brain to the periphery of your body, and nerves can also send messages back to the brain. Nerves in the upper extremity carry important information about sensations that you can feel, and movements that your brain wants your body to make.
As pain becomes more regular and severe, it can affect a person’s ability to do everything from activities they enjoy – like golf or other forms of recreation – to those things they need to do just to get through the day, from buttoning a shirt to gripping a cup of coffee in the morning.
