“What are the treatment options for carpal tunnel syndrome?”

You can take pain medication, you can have surgery, you can try acupuncture, you can do physical therapy, you can opt for nerve block type injections (although the result often is numb and weakness, which is already associated with carpal tunnel), you can wear a wrist brace, you can do nothing, or you can do chiropractic care.
I would recommend chiropractic care, acupuncture, and physical therapy first, because those are least invasive, as in they don't require you to ingest, inject, or open you up. Then if those don't work, I would opt for the brace, try medications, and last resort surgery. Surgery is the one step you can't go back from. It also doesn't have the best track record for results in carpal tunnel, and sometimes people who have one surgery may require another one down the line. I'd also try each one individually for a while then add another thing so then you know what's working for you and what's not. Also when you are working with your body's natural ability to heal, it may take time, so allow yourself the grace and patience to heal.

Medically, the recommendation is surgery to loosen the flexor retinaculum in the wrist. The problem with this approach is, the source of the problem maybe coming from the neck. Chiropractic would adjust the wrist, the entire upper extremity, and the neck. Also utilize physical therapy modalities to reduce inflammation and pain.

Depending on the symptoms, treatment options are watchful waiting, activity modification, braces at night, oral medications, hand therapy, and, finally, surgical release.
