I have a kidney stone but do i also have a uti. should i go to the er?

Yes...maybe?: If you have a kidney stone and the pain is manageable, then you should be ok. However, if you think you might have an infection, then you should probably at least be seen at an urgent care center and have your urine checked. If there is an infection, then you would need antibiotics at the very minimum. More likely you would need to have any blockage from the kidney stone treated asap.
