The treatment a person receives depends on the severity of their condition. Mild to moderate inflammation might only require rest and over the counter medication or possibly steroid injections to reduce swelling. After a few weeks, a worker could possibly return to their job.
More serious symptoms could require surgery, where the surgeon cuts the ligament that is pressing on the median nerve. As the ligament grows back, it leaves more room for the median nerve, which should prevent compression from recurring. Surgery is often followed by extensive rehabilitation. Some workers might need to wear splits that can restrict their range of movement.
If you experience any pain or numbness in your hand, get to a doctor right away. Your doctor can rule out other causes for your symptoms (such as arthritis) and order an X-ray to see what is going on in your hand and wrist.
