What should you know about a TENS unit on the perineum?

The perineum is the skin and soft tissue between the genitals and anus. It contains sensitive nerves and muscles that can be affected by childbirth, surgery, pelvic-floor tension, skin conditions, infection or nerve pain. A TENS unit may be considered in selected rehabilitation plans, but the placement must match the diagnosis. Adhesive pads should not be applied to mucosal tissue, broken skin or an area with reduced feeling.

Pause self-directed perineal use and ask a doctor or pelvic-health physiotherapist for a personalised plan. If they recommend stimulation, confirm whether pads belong on nearby intact skin, how far apart they should be, and how to control intensity. Wash and dry the skin, use the device only while awake, and turn it off before removing electrodes. Stop if you notice burning, increased pelvic pressure, bleeding, rash, swelling or altered sensation.

Seek urgent help for severe or rapidly worsening perineal pain, inability to urinate, heavy bleeding, high fever, marked swelling, or loss of bladder or bowel control. Prompt review is needed for new discharge, sores, a wound that is not healing, persistent numbness, or pain after a recent procedure or delivery.

Ask what is causing the symptoms, whether TENS is suitable now, whether pelvic-floor relaxation or another treatment is needed, and how to protect healing tissue. Explain any pregnancy, recent birth, surgery, infection symptoms, implanted electronic device or change in sensation.
