Hey all. So I went to the doctors today and had him remove a few moles. Before cutting the moles out, the doctor injects a local anaesthetic to numb the area to ensure you don’t feel anything.
I’m curious, how does anaesthetic work – you can still feel that somethings happening at the site, but you feel no pain? Would be very interested to know.
Thanks in advance!

A Biomedical engineering here,
Local Anaesthesia weakens the receptor nerves where it is applied.
Simply means that it’s like a network jammer, and our brain will not feel anything from that part of the body, because the anesthesia stops the nerves from sending signals to brain.
So we can perform painfull operations or surgical things, at patient’s max comfort ( pateint feels numbness at that point)
