Tingling in two fingers of your left hand while working at a computer can be a sign of a variety of problems. Most often, it is related to nerve compression in the wrist (carpal tunnel syndrome) or elbow (cubital tunnel syndrome).
Possible causes:
- Carpal tunnel syndrome: In this case, the median nerve is compressed in the carpal tunnel, located at the base of the wrist. This can cause tingling, pain, and numbness in the thumb, index finger, and middle finger.
- Cubital tunnel syndrome: In this case, the ulnar nerve is compressed in the cubital tunnel, which is located on the inside of the elbow. This can cause tingling, pain, and numbness in the ring finger and little finger.
- Incorrect working posture: Sitting in an incorrect posture for long periods of time, with bent elbows and wrists, can disrupt blood circulation and nerve function, causing tingling.
- Overload: The monotonous, repetitive movements performed while working at a computer can cause muscle and tendon strain, which in turn can press on nerves.
- Other reasons: Rheumatoid arthritis, diabetes, thyroid disease, and trauma can also cause tingling in the hands.
What to do:
- Change your working posture: Stand up and stretch regularly, changing the position of your arms and hands.
- Use ergonomic aids: An ergonomic mouse, keyboard, and armrests can help reduce strain on your wrists and elbows.
- Do the exercises: Do hand and wrist exercises regularly to improve blood circulation and strengthen muscles.
- Relax your hands: Take a break every hour and rest your hands.
- Use cold or warm compresses: Cold compresses can help reduce inflammation, while warm compresses can improve circulation.
Although only a doctor can make an accurate diagnosis, there are several things you can do to reduce tingling and address its cause:
1. Ergonomics:
- Correct working posture: Sit up straight, with your back supported, shoulders relaxed, and elbows bent at a 90-degree angle. Make sure your wrists are straight, not bent up or down.
- Workplace layout: Adjust the height of your chair, desk, and monitor to suit your height. The monitor should be at eye level so you don't have to tilt your head forward or lift your chin.
- Ergonomic aids: Use an ergonomic mouse and keyboard that supports proper wrist and hand position. Consider purchasing armrests and a vertical mouse.
- Regular breaks: Every 30-60 minutes, get up and stretch, walk around the room, do some arm and hand exercises.
2. Exercises:
- Wrist stretching: Extend your arms forward with your palms facing down. With your other hand, bend one palm down, then up, holding each position for 15-30 seconds. Repeat with your other hand.
- Finger stretching: Extend your arms forward with your palms facing up. Curl your fingers into a fist, then straighten them again, holding each position for 15-30 seconds.
- Nerve gliding exercises: These exercises help release pinched nerves. Search the internet for “nerve gliding exercises for arms” or consult a physical therapist.
3. Other recommendations:
- Cold/warm compresses: Cold compresses can help reduce inflammation, while warm compresses can improve circulation.
- Massage: Gently massage your palms and forearms to improve blood circulation.
- Avoid repetitive movements: If possible, vary the activities you perform to avoid prolonged strain on your hands and wrists.
If the tingling persists or worsens, be sure to consult a doctor! Your doctor will be able to determine the exact cause of your tingling and recommend appropriate treatment. This may include physical therapy, medication, or even surgery.
