Carpal tunnel syndrome treatment and diagnostics abroad

Carpal tunnel syndrome is compression of the median nerve as it passes through the carpal tunnel in the wrist. It can occur:

• on its own, sometimes associated with forceful or repetitive hand use;
• with conditions that make nerves more sensitive to pressure (such as diabetes);
• when thickened tissue in the tunnel presses on the nerve.

Not every painful or numb hand has carpal tunnel syndrome. Other nerve, neck or joint problems may need different care. Assessment considers the affected fingers, duration, sleep disturbance and any loss of strength. Bring previous tests and details of splints, injections or operations to a specialist opinion. Treatment depends on severity and evidence of nerve damage; it is not chosen from symptoms alone. Persistent numbness or worsening weakness deserves timely local assessment rather than waiting for travel.

Symptoms

• pain in the hand or forearm, especially at night or with effort;
• weakness and wasting of the muscles at the base of the thumb;
• numbness in the thumb, index and middle fingers;
• tingling provoked during examination by tapping the wrist (Tinel's sign), which does not confirm the diagnosis alone;
• often both hands are affected.

Diagnosis and treatment abroad

• Diagnosis — a neurological examination; nerve conduction studies, sometimes with electromyography, or ultrasound are selected when they could clarify findings or relevant nerve damage.
• Non-surgical treatment — a night splint, changing hand use and selected corticosteroid injections, particularly for milder symptoms. Injections may relieve symptoms temporarily, but lasting benefit is not established.
• Carpal tunnel release — open or endoscopic surgery, usually as a day case under local anaesthesia.

What changes the recommendation?

A structured clinical assessment can diagnose typical disease without routine nerve testing or imaging for everyone. MRI is not a routine diagnostic test. Weakness, muscle wasting or persistent sensory loss warrants reassessment; repeated injections or exercises should not delay it.

Release may be considered for severe disease, concerning nerve damage or insufficient response to suitable nonsurgical care. The operation divides the ligament forming the tunnel roof. Mini-open and endoscopic methods have similar long-term patient-reported outcomes. Selection depends on the individual situation and surgeon’s approach.

Discuss infection, scar discomfort, incomplete release and nerve or vessel injury. Longstanding severe nerve damage may not fully recover. Return to work depends on wound healing, function and hand demands; no fixed recovery date can be promised. Routine supervised postoperative therapy is not necessary for everyone, but selected difficulties may require support.

Preparing for care

Ask which finding supports treatment and whether another test would change it. Agree medicines, wound care, activity advice and local follow-up before travel. Request an estimate separating consultation, investigations, procedure and reviews.

Send a request with existing nerve test results, if available, to ask Clinics Direct coordinators about a specialist opinion and individual estimate.

Frequently asked questions

Does every numb hand mean carpal tunnel syndrome?

No. Assessment distinguishes other causes.

Does everyone need nerve testing?

No. Clinical findings and uncertainty guide selective testing.

Does an injection fix the problem permanently?

It may help temporarily; lasting benefit is not established.

Is endoscopic surgery always better?

No. Long-term reported outcomes are similar to mini-open release.
