After experiencing a herniated disc, sacroiliitis, and chronic pain, my PT recommended I buy a TENS unit. This has been a useful pain management tool (along with other measures I take to manage pain: physical therapy, ice & heat, medication, etc…). Only complaint is that on one of the wires the snap clasp broke so now I I have to use the other set in the box which forces me to use all six pads instead of just 4, but no big deal because I find places to use them all anyway.
