When I pinched a nerve in my upper spine, it caused a terrible numbness and tingling. Some people have described a pinched nerve as feeling like they have "Pins and needles" in the area. Mine was more...much more like a burning sensation. And everytime I tried to use my arm... when I would try to rotate my wrist, I would have severe weakness. It can also cause inflammation. I rested my neck, shoulder, and my arm, and used rotated heat & ice. It took a good 3 weeks of repeated ice, heat and rest for it to finally release the pressure on the nerve. Thankfully, I do not have permanent damage. But, when you have a pinched nerve, it can be minor (which is what mine was) or it can be severe. It can cause permanent damage if you don't do the right things and get treatment soon enough. Pain in the hip could be from the sciatic nerve. Which goes down your spine, down around your rear, hip, and into your leg. You really should see a doctor if you think you have a pinched nerve. Trust me, diagnosis is imperative to recovery. I hope you feel better soon.
