An electromyogram may also be performed. This is a test that uses a thin needle electrode inserted into specific muscles. This will evaluate the electrical activity when in use and at rest, giving the doctor an opportunity to evaluate whether muscle damage has occurred.

Another test that may be performed is a variation of the electromyography called the nerve conduction study. In this test, a small shock is passed through the median nerve. The doctors will then determine whether the impulses slow in the carpal tunnel, a sign of impingement.

Many carpal tunnel cases are a matter of simple ergonomics. Adjusting a chair or keyboard level can ease symptoms, and with rest or support of the wrist, the symptoms should fade. Ice packs to reduce occasional swelling are also effective.

Some carpal tunnel sufferers wear wrist splints that help stabilize the wrist and prevent the wrist from getting into painful positions. It can be used during work or at bedtime to firmly hold the wrist in place.

Doctors may also explore using non-steroidal anti-inflammatory drugs like ibuprofen to help pain, or corticosteroids if the over-the-counter medications are not effective.   

If none of these help, doctors may consider surgery to relieve pressure on the median nerve by cutting the ligament that is pressing on it. There is a risk of developing scar tissue that can cause further problems, as well as surgery that causes further nerve issues. The usual surgical risk of infection is also a consideration.
