Chronic SI Joint Pain

I’m a 25M suffering from chronic pain in my left SI joint. The problem started when I was sledding on a hill, lost control, and I ended up crashing into a tree when I was 17. The impact caused my left knee to hit my face, but I was able to stand up and walk afterwards with sharp pain in my left glute. Over time, I ignored it and didn't think much of it. During the meantime, I was doing physical therapy for about 2-3 months, but was sent to see an orthopedic surgeon, who then ordered a hip arthrogram. According to the report, there was a stress fracture in the left iliac bone parallel to the sacroiliac joint, and nothing could be done about it treatment-wise. Later on, I went to see a pain management doctor who ordered an MRI of the lumbar that came back normal, and then proceeded with a bilateral SI joint injection with no relief.

The pain and discomfort that I feel on a daily basis feels like when you make a fist, and you use your knuckle and press it into your SI joint, and it is always there constantly like a dull or aching pain. I feel it the most when I lie on it or sit too long. Most days, I would experience sharp glute pain in either the left or right. Some days I would feel sharp pain in both my front hips or the lower back L4-L5 area. (And every time the doctor asks where the pain is, I am pointing directly to the left SI joint.)

A few months go by, and I ended up moving to another state. I saw a new orthopedic surgeon who ordered blood work, and it turns out I was positive for HLA-B27 with normal ESR and CRP (never has been elevated) markers, and was referred to a rheumatologist. The rheumatologist started by giving me biologic medications for approximately 4 months each. The rheumatologist referred me to a new pain management doctor and ordered a CT scan of my pelvis. The rheumatologist declared that I have ankylosing spondylitis, but here is the CT report.

“Skeletal System: Both sacroiliac joints show articular cortical
erosions and subchondral sclerosis suggestive of bilateral inflammatory
sacroiliitis. HLA-B27 correlation is suggested. Both hip joints are
normal. Pelvic bones are otherwise normal.“ (they can see that stress fracture has healed)

And here is my most recent CT of the lumbar imaging report findings done this year.

“No acute osseous abnormality. An L4-L5 Disc bulge results in mild bilateral neural foraminal stenosis. L5-S1 Disc bulge.

Not sure what to do anymore, would like other people’s input. I was suggested to do a trial of the spinal stimulator, but I've read more horror than good stories about them. I was going to consider PRP but the problem is the fact that we aren't able to find where the actual pain generator is. Whether it's in my SI joint or somewhere else.
