FALSE!
Many health care professionals recommend the use of a nighttime brace, anti-inflammatory medications, and/or occupational therapy to help relieve symptoms. These measures may provide relief, but the effects are usually temporary, and there is definite risk of nerve damage if the pressure on the nerve is not reduced, even in the face of reduced symptoms. A recent study on the effectiveness of nonsurgical treatments concluded that oral steroids, wrist splints, yoga, and carpal bone mobilization provide some short-term benefit. Ergonomic keyboards, diuretics, vitamin B-6, exercise, neurodynamic mobilization, magnetic, therapy, chiropractic treatments, and laser acupuncture have not been shown to provide any lasting benefit. Carpal tunnel surgery is the only treatment that permanently relieves pressure on the nerve, and thus permanently relieves the symptoms.
