Hi user_ chf from Georgia from Australia. Had spinal L4-5 and Sacroiliac pain 10/10--that means you are simply stopped and can't move. Medicos call it "excruciating pain". If it is that -- ask your Nephrologist (kidney guy) "what is the upper level of pain meds (name) can I take per day , that will not mess with my kidneys" Most important !!
He will give you the meds and levels. How to taper on and taper off use also. Then you can "go for it". I was able to totally stop the 10/10 pain the entire day and night with his recommended meds -- with confidence - for four months. Having now, Radio Frequency Ablation operation. RFA. Minimally invasive for the elderly. Yes.
