The iReliev Pain Management System is an over-the-counter TENS (Transcutaneous Electrical Nerve Stimulator) device. It sends small electrical pulses through the skin to the underlying peripheral nerves. It is a Class II FDA registered medical device and does not require a prescription.
It is intended for sore and aching muscles in the upper and lower extremities caused by strain from sports, exercise, or normal household and work activities. It can be used for short-term injuries such as strains and sprains, and for long-term pain such as persistent back pain. There is no limit on how long or how often it can be used, and it is non-addicting.
The device has two channels that can be controlled independently, and it supports up to 4 electrodes for larger areas or multiple body parts. Eight preset programs, P1 to P8, treat acute and chronic pain differently. The LCD shows channel intensity, program mode, timer, lock status, and battery level. A lock feature prevents accidental changes to settings or intensity.
