Sharp kidney area pain followed by sore back and abdomen. No trouble with urination. Pulled muscle? Or a more serious issue?

Muscle if positional. If the pain is better in certain positions and not constant, unlikely more serious condition. If fever, lack of appetite, constant pain (and/or waking you up at night), or begins to hurt with urination suggests more serious issue. If pain recent within past couple days, responds to advil, (ibuprofen) heat/ice, intermittent and better in certain positions, more likely muscle strain/spasm.
