“Chronic pain deep in the gluteals, lower back, and feet?”

Chronic pain deep in the gluteals 6 years after ski fall (2018) on my lower back and buttocks. Almost immediately it felt like someone shoved softballs down each butt cheek and lower back. I have had multiple procedures (L5-S1 fusion in 2017, drugs, (Tramadol, Diazepam, Gabapentin), spinal cord stimulators, and Medtronics unit in 2018; Nevro replaced that this past March, etc. Some relief for about 3 years, then the pain returned in March 2021. Sitting feels like I am sitting on 2 hockey pucks. Since the return from debilitating pain, I have seen 3 pain specialists (corticosteroid injections (have had many of these; none have ever worked). Oh, can't forget nerve ablations. No help. I was tested for RA, Lymes, and I can't even remember what else. The last MRI showed stable fusion and SCS paddle. My blood pressure is good. All meds are in the normal range except a few borderline. No one seems to be addressing the issue of the "Hockey pucks" deep in my glutes when sitting. Cycling and walking also aggravate the glutes, back of thighs, and feet, especially the right side. There doesn't seem to be any doc who can pinpoint and address the problems. I can't believe that I am the only person in the world who has experienced this problem.
