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.
Hello, As I get it you said that you have back pain, and it radiates to the hip. What is your job, has it to do with lifting weights? Are you doing any activity when the pain started, or it started gradually? Do you have other associated signs like numbness, or tingling sensation? Does the pain radiate lower than the knee level? It is more painful in the night or in the morning? How does it last when it starts? I suggest you to do first a lumbar x-ray and to visit an orthopedic. Hope I have answered your query. Let me know if I can assist you further.
