I love mine, but it also depends on where your pain is located. Because it's muscular, you're in luck.

I find it helps while it's on. It helps distract me from the pain, and can help force those muscles to constrict to the point of exhaustion so that they can finally relax. Although a lot of times I end up more sore than anything after the fact so YMMV

I got one from the VA and gave it a good shot, didn't really work much for me though.

Knew another guy who loved his and used it all the time.

Go into it with an open mind assuming it'll work, for some people it really does.

I have never tried them, haven't even heard about them before now. I look forward to hearing your review of it, take as much time as needed.

Well, some organs/glands are able to be soothed by tens. I personally have used one for my pancreas and it seems to work well when there's pain signals I can sort of map out to areas on my skin. Didn't work great, and since it's been over a year I've tried other things that work better, like fasting. Occasionally if my arm or other appendage has muscle spasms or soreness then I can use it and it helps.

Might only be useful for those with muscle related pain.

Have used one for muscular problems in the past with success. The pads have to be in the right place, and the settings right before it works properly, so there may be some experimentation needed.

If it's running and a pad comes loose you get an 'exciting' shock.

Don't think they can be used permanently.

If it's muscle spasms, have you checked for electrical problems like a trapped nerve?

Good luck with the pain management.
