What should you know about a Hollywog TENS unit?

TENS stands for transcutaneous electrical nerve stimulation. The unit sends controlled pulses through adhesive electrodes placed on the skin near a painful area. People commonly describe the sensation as tingling; it should not feel sharply painful or cause a burn.

TENS can make movement or daily activity more comfortable for some people, but it does not repair a torn tissue, remove pressure on a nerve or establish a diagnosis. The helpful setting and electrode position vary with the problem and the device instructions.

Follow the Hollywog instructions and begin with a low intensity while seated. Place pads only on intact skin, keep them away from the front or side of the neck, head, eyes and broken skin, and turn the unit off before moving electrodes. Check the pads and wires for damage.

Do not use TENS over an implanted electronic device unless the treating specialist specifically approves it. Ask a clinician before use if you have reduced sensation, a seizure disorder, pregnancy-related concerns or significant skin disease. More guidance is available in [TENS Unit](/technology/tens-unit/).

Stop using the unit and seek advice if it causes a burn, persistent skin irritation, marked dizziness, worsening pain or new weakness. Urgent assessment is needed for chest pain, fainting, sudden limb weakness or loss of bladder or bowel control.

Where should the electrodes sit for my diagnosis? Is TENS suitable with my medicines or implanted device? What symptoms would mean I should stop using it?
