<bot>: Cellophane You for contacting Chat Doctor. There are multiple causes of lower back pain. I would have been in a better position to guide if u had told your age. I would suggest following differential according to priority:> Muscular spasm> Renal Calculi> Pelvic Inflammatory Disease> PyelonephritisThey can be ruled out on the basis of clinical and lab evaluation. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. Wishing you good health.
