Jaw Issues

My remaining recent issue since the surgery is that my jaw will not open all the way. Opens about only an inch... not quite wide enough to say, eat a burger. I use to have to pop my jaw open every morning, but yea, can't do it now. Not that it hurts trying, but it feels like it might be so dislodged it doesn't even know where to pop into place or something. I can't even crack my neck on the side of the surgery. Is this temporary? Do I need a chiropracter to fix my jaw? Any remedies?? I would like to be able to eat my burger tonight!
