Intensity at home with a TENS unit

TENS sends mild electrical pulses through electrode pads placed on the skin. The setting controls how noticeable those pulses feel; it does not measure how serious your pain is. A useful sensation is rhythmic tingling that remains tolerable while you sit or move normally. Sharp, hot, stinging, or painful sensations suggest the setting is too high, a pad is poorly placed, or the skin needs a break.

The right setting can change between body areas, activities, and days. Numb skin may not give reliable feedback, so avoid increasing the output to compensate. TENS may ease pain for some people, but it does not identify or treat every cause of pain.

Check the device instructions and place intact pads on clean, dry skin near the painful area, never across the front of the neck or over broken skin. Start with the device switched off, then raise the intensity slowly. Keep the sensation comfortable and check the skin after use for persistent redness, irritation, or a blister.

Do not share pads, sleep with the unit running, or use it while driving or bathing. Ask a clinician before use if you have an implanted electrical device, reduced sensation, a seizure disorder, pregnancy-related questions, or an unexplained pain pattern.

Stop the unit and seek prompt medical advice for a burn, lasting skin change, new weakness, spreading numbness, severe dizziness, or a marked worsening of pain. Chest pain with breathlessness, fainting, sweating, or pain spreading to the arm or jaw needs urgent emergency assessment rather than home TENS.

Ask which pad positions and programme suit your pain, what sensation is expected, how long each session should last, and whether your medicines, skin condition, pregnancy, or implanted device changes the advice.
