Jus came from the er and the doctor said i have flank all my test came back negetive n my unrine was good but still have side pain n pain on my left rib what flank?

Flank Pain: Might be referring to "flank pain" which can come from pulled muscles or sore ribs. Organs in that area that can cause flank pain are the kidneys. Sounds like they looked at your urine and blood to try and detect a kidney infection or possible stone. Worsening pain or additional symptoms would warrant a re-evaluation. Family doctor/urgent care are appropriate if not emergency. Hope this helps!
