I have left flank pain, left rib pain, muscle knots in lef flank pulling one rib out of place, onset of headache/nausea today, increasing pain - had x-ray last week if upper back and left flank, some mild arthritis that I’m told doesn’t account for rib pain. Urine screen about three months ago, everything looked fine. Abdomen tender when examined by Dr. last week. Was sent for x-ray and to continue PT, f/u w/ PCP tomorrow night, worried about increasing pain, unsure if am should go to ED or wait til PCP appt tomorrow night.
