The glorious thing about humans is that while we are all the same, we are all different.
I had cervical stenosis and was on low dose oxy for 8 weeks. Fortunately no surgery was needed. The initial pain was so bad I needed it but after the second shot I started weaning myself off of it. No buzz, no high, just blessed pain relief.
They gave me oxy when I had my shoulder surgery. Took 1 the next day and it weirded me out that I stopped them. Otc plus ice machine plus doing the exercises religiously.
