HI There's a book called Pain Erasure by Bonnie Prudden. It's all about Trigger Point therapy. My husband did Trigger point therapy for my back and it helped tremendously with my low back spasms and bladder spasms.
As far as the spinal cord stimulator......I say go for it! If it doesn't work take it out. But I'd give it a try.....at least the trial and see if it works at all.
I do know what you mean about relying on pain meds and not wanting to be without them. I have a sleep disorder and I panic if I'm low on my sleep meds. I've had the problem for 40 yrs and taken meds for it for 30 yrs....
Let us know what you decide to do.......we're with ya, with what ever you decide!
