How does a nerve block (anesthesia) last so long?

7.88K views

I had shoulder surgery yesterday. Prior to the procedure an anesthetist performed a nerve block. It’s been 16 hours and I still cannot feel or move my arm. I am just now starting to be able to wiggle my fingers.

I don’t understand how the anesthesia can last so long. I saw the needle with the medication and there really wasn’t much of it. How is the medication not quickly carried away from the injection site?

Thank you in advance!

It varies but I was told 24 to 48 hours. It lasted just under 48 hours and I was not happy when it wore off
