Why can you still feel pressure when you’ve been numbed?

676 viewsBiologyOther

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.

As for stitches depending on where you are they apply said numbing agent. In my experiences (59 stitches total over 9 injuries) it’s not pressure from the numbed area, it’s everywhere else. Surface layer anaesthetic doesn’t permeate deep enough to affect the nerves standard freezing agent delivers. The pressure is literally from the added fluids and that numbing paste doesn’t reach your bones or anything else but a few sensitive layers of skin.

One is for the tiny needle (paste anaesthetic), the other is for the thread coming through your body (freezing agent).
