Skin irritation
Skin irritation from electrode pads can show as redness, rash or itching. The NHS says to turn off the unit and remove the pads, and University of Iowa says to tell your care team.
The NHS says that if your skin becomes itchy, irritated or red, turn off the machine and remove the pads. It notes redness may be harder to see on brown or black skin. University of Iowa Health Care says to stop using TENS and talk with your doctor or health care team if you have skin irritation (redness, rash, itching), and that people who are allergic to nickel or adhesives may have skin irritation with TENS. Do not place electrode pads on broken or irritated skin. Tell your clinician, who can advise on alternatives. Read the TENS unit safety guide.
