I have been experiencing lower back pain and stiffness for about 3 weeks in the lower middle back. I do not notice it on the outside area of the lower back like a kidney infection, but my urine is very yellow. Also, I am experiencing pain the my hips and groin area. The outside of my right hip hurts when I try to lay on that side. I have experienced more difficulty raising my left leg to put on clothes, etc. It hurts more to sit or lie down than to stand or walk. When I first get up, I am very stiff and it is more difficult to get my legs moving without a limp. I have always been pretty active and on my feet with my job as a teacher. I thought it was just age related and would subside when school ended and I was off my feet for the summer, but it has continued with no relief.
