What should you know about TENS unit for muscle recovery?

TENS applies small electrical pulses through skin pads. The resulting tingling may influence pain signalling and can make ordinary movement more comfortable for a while. It does not repair a torn muscle, replace sleep, or remove the need to adjust training. Recovery looks different after routine exercise, a strain, surgery, or an illness, so persistent or unusual symptoms deserve a proper assessment rather than repeated attempts to cover them.

For a minor exercise-related ache, reduce the activity that provokes symptoms and return to gentle movement as comfort allows. A physiotherapist can advise on stretching, mobility, strengthening, and whether TENS is appropriate. Place pads on intact skin according to the manual, use the lowest comfortable setting, and stop if the skin becomes irritated. Keep pads away from the front of the neck, head, chest, and any area with reduced sensation. Follow professional advice if you have an implanted electrical device or another medical condition.

Arrange assessment for pain that keeps worsening, substantial bruising or swelling, inability to use the limb normally, repeated cramping, or weakness that does not improve with rest. Seek urgent care for severe pain after trauma, a cold or pale limb, new one-sided weakness, chest symptoms, or difficulty breathing. Stop TENS for burning, a rash, dizziness, or an unusual heartbeat.

Ask what may be causing your muscle symptoms, which activity is safe today, and how to progress back to training. Confirm pad placement, session limits, and signs that mean you should stop using the unit.
