What should you know about intensity 10 digital TENS unit?

TENS sends mild electrical pulses through adhesive electrodes placed on the skin. Digital devices label intensity differently, so 10 on one model does not equal 10 on another. The aim is usually a clear, comfortable tingling rather than sharp pain, burning, or forceful muscle discomfort. TENS may change how pain feels for some people, but it does not identify or correct the underlying cause. Read the manual for the programme, electrode placement, and maximum setting for your model.

Inspect the skin before and after use, apply electrodes to clean dry skin, and increase intensity gradually. Stop if the sensation becomes painful, the skin burns, or irritation develops. Do not place electrodes across the front of the neck, over the head, through the chest, on broken skin, or over areas with reduced sensation unless a qualified clinician has specifically advised it. Keep the device switched off while placing or removing pads, and replace worn electrodes according to the instructions.

Stop using the unit and seek advice for a persistent rash, blistering, worsening pain, dizziness, or unusual symptoms. Get medical guidance before using TENS if you have an implanted electrical device, an active skin problem, reduced sensation, or are pregnant. Do not use electrical stimulation to delay assessment of new weakness, severe injury, chest pain, or rapidly worsening symptoms.

Ask whether TENS is suitable for your pain, where electrodes should go for your body area, and which programme and intensity are reasonable. Ask how long to try it, how to protect your skin, and when persistent pain needs a diagnostic assessment instead.
