Hi, So I Am 17... I Had A Car Accident

Hi, so i am 17... i had a car accident about 6 months ago. it was pretty bad. after that i had very painful leg pain. mainly located in my hip and just below my knee. i went to a chiopractor for it for awhile,but it didn't help. it only got worse from there. now i am at the point to where its very painful and hard to walk. and just recently, about a month and a half ago, my ankle started hurting. i have tried pain meds and therapy. i was told once i had sciatica. i am now thinking they were wrong. my pain has been getting worse, and i can barely walk.

thank you!
