I did something to my lower left back a few days ago. I have been using an EMS/TENS device which has helped. My chiropractor would hook me up to one for the last 15 minutes of every visit. It seemed to be the only thing that he did that helped. So eventually I just bought a small hand held one. EMS mode works best for me. I use it for all kinds of injuries. There are some situtions where you shouldn't use one. Read up on it first. I bought an iReliev TENS + EMS combo unit. Maybe ask your chiro about it.
