You’ve seen TENS units everywhere…
But are they actually helping your pain—or just masking it?
TENS units send low-level electrical pulses through the skin to help reduce how your body perceives pain. For some people, they can provide temporary relief.
But here’s what most people don’t realize:
👉 They don’t fix the underlying problem.
Technique or Treatment
It is imperative to read the manufacturer’s instruction booklet, as each unit might have slight variances in recommendations. TENS units are now small and lightweight. Patients can place them in their pocket, on a desk, or hold them. Treatment sessions occur at the patient’s convenience except while operating heavy machinery, driving, bathing, showering, or swimming.
Complications
Despite its safety profile, there are cautions associated with TENS use.[16] Due to potential complications, individuals with pacemakers, epilepsy, or those in the throes of pregnancy are universally advised against TENS use. Theoretical risks extend to transdermal drug delivery systems and dermatologic concerns, urging a cautious approach.[15] Steering clear of TENS during activities like driving or operating heavy machinery mitigates potential complications.
