I was given muscule relaxers and ibuprofin for the swelling...i do not think is a musculer problam the pain is caused by, i was given a urin test that came back negetive
With such presentations in my clinic, I would first rule out serious conditions using abdomen USG scan so that to rule any internal issue, if present need to be treated accordingly. Also I want to know your renal (kidney) status, as the pain in that area indicates of some kidney problem but based on your history it can be ruled out.  Once I am sure this is not life-threatening I would think of local muscle problem for which relaxants will help you. Also you need to check for any other diseases like ovarian cyst or fibroid, diabetes, hypertension if your age is more than 35.  Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions.  Wishing you good health.
