TENS Machine Side Effects: Is TENS Therapy Safe?

May 01, 2017 in TENS Therapy


TENS therapy has been used by doctors and medical professionals in their private practice and clinics for decades. TENS machines have now become available for consumers at home. Operating a TENS machine at home means that there is no professional supervision and more questions around the proper application. Many people are concerned that TENS therapy could produce TENS machine side effects. Are there TENS machine side effects? How can you avoid them and safely use your device?

TENS Machine Side Effects

Studies have shown that TENS therapy is a safe and effective way to relieve pain. However, it is important that a TENS device user properly uses their machine to avoid side effects. Misusing a TENS device can result in the following symptoms:

  • Skin irritation
  • Uncomfortable muscle twitching
  • Uncomfortable tingling sensation

*Muscle twitching and tingling is normal during TENS therapy when it feels comfortable. If the muscle feels uncomfortable or painful the TENS machine may be being misused.

    Hi there,

    Is a Tens machine safe to use for someone with a pacemaker? We have clients whom would like to use the tens machine on their feet or on their back. Is your machine safe for them to use on different areas of the body? Could you please get back to me?

      Hi Nola,

      A Tens machine should not be used on an individual with a pacemaker without proper consultation from their doctor. The tens machine should not be placed near the pacemaker or over it. I would recommend your clients see a health professional who is familiar with using tens therapy in their practice before trying it themselves.

      Thanks for your question, hope this was informative.
