@erinragancooper: If you have back pain, muscle tightness, or frequently get flare ups of sciatica, you need to have this home unit on hand. I use this when ever I have a flare up, or if I have an intense workout and need some relief. @DRwiik #backpainrelief #lumbartraction #electricalmusclestimulation #sciaticarelief #dealsforyoudays
