...Cogito pretty much said what I really wanted to say about
the Dr being speechless about
it not working, and then already scheduled another. Bottom line,... there is a good profit in it for them! However!...it often takes a second round for many patients to see positive results...so I myself would at least try it again, and if then no good results are seen, then I would not attempt a third.
I have had several of them and decent luck with the cervical...but no responce in the lumbar area of the spine.
Again...I have to think that the Dr is pulling the wool over your eyes a bit in his dismay. Also, surgery should be the very last option, should that conversation come up,...and it is not an easy decision to make. What ever you do...don't let the Dr make that for you....it's yours to make not his. If you should happen to go the pain med route, then again be careful with them, and educate yourself as much as you can if you happen to travel down the long tough road of chronic pain.
The best advice I can give you, is to seek support from those who suffer chronic pain on a 24/7 basis, like most of us do here on this forum. Friends and family simply will not and cannot grasp the concept and you will be better off sharing and seeking support from those who suffer likewise.
Again, good luck and take care!
