Cryotherapy is an excellent way to reduce inflammation and temporary pain. Ice causes constriction in the veins of the affected tissue, limiting blood flow and acting as an anesthetic. Once the cold compressor is removed, blood will rush back to the affected area providing nutrients that will help with the healing process. 

Cryotherapy is often used in the treatment of back and neck pain. It lessens the severity of muscle spasms, reduces pain by causing numbness, and aids in lessening soft tissue damage.

Patients suffering from rheumatoid arthritis, Raynaud's Syndrome, colds or allergic conditions, paralysis, or areas of impaired sensation should not use cryotherapy.
