The therapeutic use of cold or heat is a well-known physiotherapeutic treatment. However, the usage of heat or cold on the affected area depends on the type of pain.  Heat therapy is an effective way to relieve pain caused by muscle strain and tension.  Cold therapy is recommended for acute inflammation or sports injuries like sprains, contusions, bruising and swelling.  If you are in doubt on whether to apply heat therapy or cold therapy, please take expert advice from a medical professional.
