Back pain, been there, done that.
It sucks.
I used to have a nightstand lined up with a multitude of drugs.
Some for pain, some to sleep, more for pain, etc.
I finally had to get surgery, 3 times.
The numbness and pain down the legs is gone, but the pain in the lower back is still there, albeit, no where near as bad.
But, I am quite the barometer these days, more accurate than the stinkin weather man!
Percocet was my favorite answer to the pain, mostly numbed the mind, whereas, I no longer gave a shit about the pain.
The need for percocet is now only when it is raining for more than a day. Other than that, I can deal with it.
I wish all the best drugs for you brother!
Rest much.
