Thank you for your question! The pain must be very worrying for you. Firstly, carpal tunnel syndrome is a clinical diagnosis which is made after a clinical evaluation by a doctor. If the pain is severe and affecting your function, we would recommend that you consult a physician as soon as possible.
Carpal tunnel can be caused by repetitive strain on your wrist, causing compression on a nerve known as the median nerve. In diagnosing carpal tunnel syndrome, the distribution of pain and numbness, as well as the type of hand actions that are restricted/ weak are important clues in determining if the problem is really caused by the median nerve.
Other conditions to rule out includes nerve root compression from your neck, causing a shooting pain down your arm to your neck.
Given the severity of the pain and its impact on your function, we recommend that you consult a doctor as soon as you can to confirm the cause of the problem, so that you can be referred to receive the management you need.
During your consultation, as mentioned above, do note the distribution of the pain, types of actions that are limited, as well as exacerbating factors of the pain and provide these information to your doctor as it may assist him/her in getting a clearer clinical picture.
We hope this helps, and all the best!
