Carpal tunnel syndrome is a condition where the median nerve gets compressed as it passes through a narrow passage in the wrist called the carpal tunnel.
Carpal tunnel syndrome
🧠 What it affects
The median nerve controls:
- Thumb
- Index finger
- Middle finger
- Half of the ring finger
When it’s compressed, those areas can feel numb, weak, or painful.
⚠️ Common symptoms
Symptoms usually start gradually and often worsen at night:
- Tingling or “pins and needles” in fingers
- Numbness in thumb and first 3 fingers
- Hand weakness (dropping objects)
- Pain that may extend to the forearm
- Night-time hand discomfort
🔍 Causes & risk factors
Anything that increases pressure in the wrist can contribute:
- Repetitive hand movements (typing, assembly work, phone use)
- Wrist injuries
- Pregnancy (temporary fluid retention)
- Diabetes or thyroid problems
- Arthritis
- Genetics (smaller carpal tunnel)
🩺 Treatment options
Mild cases:
- Wrist splints (especially at night)
- Rest and activity changes
- Cold packs
- Anti-inflammatory meds (if advised)
Moderate cases:
- Physical therapy
- Steroid injections
Severe cases:
- Surgery to release pressure on the nerve (carpal tunnel release)
⏱️ When to see a doctor
Get checked if:
- Numbness lasts more than a few weeks
- Weak grip starts developing
- Symptoms interfere with sleep or daily tasks
💡 Simple prevention tips
- Keep wrists straight while typing
- Take frequent breaks from repetitive tasks
- Avoid prolonged bending of the wrist
- Use ergonomic keyboards/mouse if needed
