numb

A numb feeling means that your body or mind doesn't feel much pain or sensation, as if something's blocking it.

You might get numb when you sit on a cold bench for too long, and your bottom starts to lose all feeling. This happens because the blood flow slows down in those areas and can make them feel like they're not even connected to the rest of you. You also might get numb after an injury if there's swelling or bruising that presses against nerves. Sometimes, people take medication that makes their pain go away but also causes numbness, especially in their hands or feet. It's also possible for some parts of your body to feel numb due to a medical condition like diabetes. When you're numb, you might not be able to feel things as strongly, and it can make everyday activities more difficult.
