Question: What Is Cryoanalgesia And When Might It Be Used To Treat Pain?
Answer: Cryoanalgesia is a pain-relieving technique which uses cold to treat nerve pain. It's been around for centuries, and in its crudest form, uses ice to numb nerves.
The more sophisticated, current type of cryoanalgesia uses a needle-like probe to deliver very, very cold sensation and thereby incapacitate nerves.
Cryoanalgesia is most commonly used to treat pain after surgery, to treat certain types of headaches, pain with scarring, and also some types of back pain.
