question: Hi doctor,My problem started with pain in my lower back and buttock, and then it moved to my lateral thigh on both sides. So, it is difficult to sleep on either side. I also started experiencing neck and shoulder pain. Now, I feel pain in my arms, back, neck, shoulder, etc. I do not know what could be causing this. My last general blood test a month ago was all right. Also, I was recently diagnosed with gallstones.
