Hip pain

Hello! I have been struggling with hip pain for a couple of months and at the beginning I thought it was maybe nothing to worry about, but it got slightly better and it has now remained as a chronic pain.

To be more descriptive ( sorry if I do not explain very well, English is not my first language), A coup,e of months ago I was struggling with back pain but it was more of a normal back pain that you get from sleeping in a bad position. I was dancing one day, and it suddenly hurt really, REALLY bad. It hurt to sit, to walk, to lay down, basically to exist. Bending down felt torturous and it was basically impossible. Over the time the pain subsided slightly, and I started noticing it wasn't my back, but around my sacrum. Now the pain is a chronical one. Sometimes it doesn't hurt at all, or it's something bearers noticeable, other times I stand up and it hurts to walk since the pain goes to my legs (usually it's only one of the two) and sometimes the pain is only on my hip area.

I am desperate to know theories or what it could be. I am not independent, so I do not want to bring any alarm to my parents about this unless it's genuinely urgent since the doctor is really expensive. I am afraid that I'll end up in an irreversible pain. Please help me 😔
