Stubborn tender point back of hip/ butt area

I’ve had this ridiculous trigger point kind of between the back of my hip and my butt. It’s painful and causes tense muscles around it and pain.

I can reach back and try to release it but I don’t make much progress.

My dr is booked for a while yet. I don’t want a long wait to get in elsewhere. I do not currently have anyone in my life that would deal with that part of my anatomy. I’ve tried a massage gun and using a fascia blaster.

Has anyone had a trigger point there? How did you release it?
