How long should I use a TENS unit?

20-30 minute sessions, 2-3 times daily for chronic pain. Acute pain may benefit from longer sessions up to 60 minutes. Do not use continuously for more than 60 minutes — take at least a 20-minute break between sessions. If pain worsens during use, stop immediately and consult a healthcare provider.

Can TENS replace pain medication?

TENS can reduce the need for pain medication in many cases, but it should not replace medication without discussing with your doctor. It works best as part of a comprehensive pain management plan that includes exercise, stretching, and ergonomic improvements. TENS provides symptomatic relief — it does not fix the underlying cause of back pain.
