Hip pain

I noticed that if I am on my feet a lot or even take a 1/2 mile walk my hip hurts so bad that I can’t stand on that leg unless I want to fall on the floor. When it’s most intense it shoots from the hip down to my knee. I have not had any injuries. It first happen about 2 weeks ago after I took a short walk. I have been to two different chiropractors and none have been able to help me. Has anyone ever experienced this or know what I’m talking about?
