Why do my hips ache from standing, and 'pop' when I walk.?
I stand for about two hours at a time and my hips just start to ache really bad, sometimes my knees too. I have decent support in my shoes. I do sometimes have a problem too when I walk, my hips almost 'pop' but not 'crack', kinda like the pop out of joint a little or something but it only starts to ache after about 15 mins of walking like that. Sometimes I can make it stop if I walk differently (stiff-like). I am only 23 and this has been happening for quite a few years, since I was 16 probably. Should I be concerned? Is there any certain vitamins or supplements I can eat more of or take to help with this? I haven't had any injuries in the past that I know of that could have caused this.
