Years of knee, ankle and hip pain. I'm tired.

I don't know if I'm even asking for advice at this point, I'm just tired.

I started walking when I was 3, they said I was flat footed. As I grew I started getting bad pains in my knees. It started as that and now I'm 17 and hardly can get to college without sobbing.

For the last 6 years the pain has got worse, some nights I can hardly move or walk. I get bad tightness in my ankles. I can't stand or sit for too long either. Stairs are impossible on bad days.

In the last 6 months I've now been getting severe random pain in my hip when I move my leg up or walk. It's really bad, I can't walk on the days it hurts.

I have been to anyone you can think off for this, just before covid they sent me to a person who could look at my feet. Every time I've been told it's growing pains. I had a physiotherapist at one point and they said it's growing pains. I don't think it's growing pains anymore and if it is why are they this bad? To the point I can't walk? I'm tired and its stopping my education and everyday life. I'm in so much pain and I want it to stop.
