You are welcome. I wish I could reach out and give you a healing touch. I keep telling doctors, "Look, for every effecr, there's a cause. My effect is that I have continued pain in my buttocks. Therefore, something is causing it. Please identify the cause and treat it". Ha! Lot's of luck.
Even if you are hesitant to have either of these procedures, I would want to know, by having the relatively non-invasive trial, if either one provides relief. But, that's just me. I wish you well on your pain journey.
God bless!
