Extreme hip, thigh, and lower back pain, accompanied by sever chills with uncontrollable shaking for about an hour. Pain has continued off and on and I am feeling quite fatigued. I stayed home from work yesterday because I could not stand long enough to get ready for work. I went to work today, but it took quite a bit longer than usual due to the hip and thigh pain. I also had some minor upper left chest twinges. I have spinal stenosis in the lumbar region, and the back is curved to the left. It feels like flu symptoms but I have no respiratory symptoms. Is this something I should go to my GP about? Sorry, I did not realize this was a pay for answer service.
