Symptoms
- Numbness and tingling in thumb, index, middle, and half of ring finger
- Worse at night, often waking you up
- Weakness gripping objects or dropping things
- Symptoms relieved by shaking the hand ('flick sign')
- In severe cases, thumb muscle wasting
Risk Factors
- Repetitive hand/wrist movements (typing, assembly work)
- Pregnancy (fluid retention)
- Diabetes
- Hypothyroidism
- Rheumatoid arthritis
- Obesity
Diagnosis and Treatment
| Step | Approach |
|---|---|
| Clinical tests | Tinel's sign (tapping over wrist), Phalen's test (wrist flexion) |
| Nerve conduction study | Confirms diagnosis and severity — measures how well the median nerve conducts signals |
| Conservative treatment | Wrist splint (especially at night), activity modification, steroid injection |
| Surgery | Carpal tunnel release if conservative treatment fails or severe/progressive |
Night Splinting Is Highly EffectiveWearing a wrist splint at night (keeping the wrist in a neutral position) is often the single most effective conservative treatment, as symptoms are frequently worse during sleep due to wrist flexion.
Is carpal tunnel syndrome caused by typing?
While repetitive hand use can contribute, carpal tunnel syndrome has multiple causes, and the link with typing/computer use specifically is weaker than commonly believed — pregnancy, thyroid disease, and diabetes are often more significant factors.
Does carpal tunnel syndrome always need surgery?
No — many cases improve significantly with conservative treatment (splinting, activity modification), especially if caught early. Surgery is reserved for severe, persistent, or progressive cases.
Can carpal tunnel syndrome cause permanent damage?
Yes, if severe and prolonged compression continues untreated, permanent nerve damage and muscle wasting can occur — this is why early treatment is important.
