Deep pain next to butt

Did sprints like 7 weeks ago. Felt a pop and since then the muscle right next to my Anus is hurting. Yes right next to my butthole not a normal glute pain it is literally right next to my butthole. After like 3 weeks it felt like it got better so i trained a bit and hurts again. Ultrasound is a 2 month wait list, and physio is so expensive here. Anyone had anything similiar ? Any pelvis exercises that could help?
