The Expain Experts
“Transcutaneous Electrical Nerve Simulation (TENS) is the recommended treatment for muscle pain in the physiotherapist handbook. TENS both increase the production of endorphines and inhibit pain signals by giving a larger stimuli to the nerves.”

“Heat is a well known treatment for soothing muscle and joint pain. Heat both inhibits pain by bombarding the nerve sensors with signals, and heat increase blood circulation, which transport impurities away from pain areas .”

“TENS is electrical stimulation of the muscles and nerves that activate the muscles, increases blood flow, increases the production of endorphins and overwhelms nerve signals that report of pain to the brain. TENS is thereby inhibiting pain.”
