How fast can I expect pain relief using TENS therapy?
Unlike some therapies, if TENS will help relieve your pain, you should feel a difference relatively quickly. TENS is based on the theory that one electrical impulse blocks another, so the impulse from the unit should start blocking the pain impulse right away. Experts say that a TENS treatment takes about 30 minutes to reach full effectiveness, and the results should last about 30 minutes after treatment.
