Carpal tunnel syndrome is a common condition in adults that can result in pain, tingling, and weakness in the affected hand. Both hands are often involved. The most common initial treatment is wrist splinting. When splinting is ineffective, steroid injections are often given and provide relief. However, it is difficult to know whether steroids are really the reason for improvement because the condition sometimes gets better on its own. When symptoms persist, surgery is performed. Although such surgery usually resolves the condition, it is associated with short-term pain and limitation of use of the operated hand as well as increased medical costs.
