painful urination with blood; especially in someone who is diabetic is a urinary tract infection until otherwise proven. yes you need to see a medical provider but not necessarily the er (this is not an emergency-- a regular medical office or urgent care facility would be fine (and less expensive). in the meantime drink plenty of water.
should a person go to the er if urinating with pain and bright color blood drops? . also having headache but no fever. blood glucose also increased after eating to ~300. thanks for your help.
