Carpal tunnel is a real pain.
I actually remember studying it with anatomy back in my academy days.
The hand is very complex and the tendinous aponeuroses also include the palmar fascia, etc.
You shouldn't have problems with the carpal tunnel due to study; otherwise, you are practicing exercises incorrectly or forcefully. There are many exercises even to loosen the tendinous aponeurosis, making, for example, the movement of the 4th and 5th fingers more fluid and less strenuous.
There are many remedies well-discussed online, but in the end, it is always a matter of inflammation. Whether the tunnel narrows due to inflammation or widens for other reasons, you will always experience discomfort regardless. Many also recommend a foam ball, and others say to avoid constant transitions from cold to hot water (chefs, for example, suffer from this a lot and I have known many who complained), but unless it is a hereditary factor, I also recommend changing your diet.
I know it sounds like stories, but a diet low in sodium or with very little sodium, associated with the consumption of fresh vegetables and fruit, avoiding as much as possible sugars, dairy, eggs, and meat, greatly reduces inflammation in the body, making it much more active and light.
Anti-inflammatory muds are also an excellent alternative, or in extreme cases... extreme remedies... cortisone injections! Personally, I am against non-natural actions, so I advise you to carefully monitor the reasons for the inflammation by trying to avoid triggering factors. Paolo had spoken about the hand specifically from an anatomical point of view, anyway; the lesson seemed very interesting to me, so he will surely be able to give you appropriate advice.
