Say you get an injection and the site has been anesthetized beforehand with a topical numbing cream, why is it that you can still feel the pressure? Is the pressure sensation not associated with nerves? If not, how does your brain detect pressure sensations?
P.S. I’m not sure if “numbed” is a word but I couldn’t think of another way to say it lol.

Different nerves for different types of sensation! This is a super fascinating area within sensation/perception, but basically we have different types of neurons to tell us about different kinds of stimuli. Some detect heat, others pressure, and so on. “Pain” casually understood is but one type of physical sensation.
