Cold application has two primary benefits:
- It reduces inflammation, which is usually a culprit in any type of back pain.
- It acts as a local anesthetic by slowing down nerve impulses, which keeps the nerves from spasming and causing pain.
Heat application has two primary benefits:
- It stimulates blood flow, which brings healing nutrients to the affected area of the low back.
- It inhibits the pain messages being sent to the brain.
