Just asking for advice :)

Hello I haven’t posted to Reddit before so like idk if there’s unspoken rules or something. Anyways, I (19f) have been experiencing some strange hip pain kinda suddenly. I’m 6’0 and 180lbs and I’ve struggled with knee pains for years now because of Osgood-Schlatter disease. It was getting better about two years ago but started declining early this year. I’ve felt throbbing and stabbing pains in my left knee and it feels like it’s spread to my left hip aswell. It hurts to bend over and try to touch my toes and my left ankle has also started to hurt too. Anyways, if this sounds like anything or if I should go to my family doctor and get it figured out, please let me know.
