Yesterday I began to have pain in middle to lower left quadrant of the back. It is constant. So bad I hold myself and avoid moving. It does not seem to be related to stomach, back, or intestines. Heat does not help nor does Tylenol. There is a slight nausea, but relatively minor. I have not hurt myself recently.
I have a slight tugging pain in my mid left back quadrant. It feels deep, not muscular. Doesn't seem to be exaggerated or relieved by movement. What can it be?
