What should you know about using a TENS unit on your wrist?

TENS means transcutaneous electrical nerve stimulation. Small adhesive electrodes deliver pulses through the skin, often producing a tingling sensation. Around the wrist, it may be considered for discomfort linked to muscles, tendons, joints, or some nerve-related pain. It does not repair a fracture, remove pressure on a nerve, or explain why the wrist hurts.

Avoid pads over cuts, rash, infection, numb skin, or a fresh surgical area. Keep electrodes away from the front of the neck and across the chest. A wrist with major swelling, deformity, or loss of feeling needs assessment rather than self-treatment.

Wash and dry the skin, connect the pads as directed, and begin with a low comfortable setting. Place electrodes around the painful wrist area, leaving space between them and avoiding the wrist crease if movement causes pulling. Use the session length recommended by the device instructions or clinician. Stop if the sensation becomes painful, the skin burns, or a rash appears; remove pads gently and inspect the skin afterward.

Ask a clinician before use if you have a pacemaker or other implanted electrical device, reduced sensation, a seizure history, or a recent operation. TENS works best as one part of a plan that may include rest from aggravating tasks, gradual exercise, or a wrist support.

Seek urgent care after a significant injury with deformity, severe swelling, a cold or discoloured hand, or new inability to move the fingers. Prompt assessment is also needed for spreading redness, fever, worsening numbness, or marked weakness. Arrange a review if wrist pain persists, interrupts sleep, or repeatedly returns despite activity changes.

Ask which wrist structure may be causing the pain, whether TENS fits that problem, and exactly where the electrodes should go. Also ask about intensity, session timing, skin reactions, exercises, splint use, and warning signs that require a review.
