Hi, thanks for using healthcare magic Diabetes would normally present with increased frequency of urination and may not necessarily present with a burning sensation on urination Burning on urination may be related to urethritis which is inflammation of the tube that connects the bladder to the rest of the body. It can be caused by bacteria that cause urinary tract infections or bacteria that is associated with sexually transmitted infections. You may want to consider a urine test to determine which organism is causing the problem. The lab can check for the bacteria associated with urinary tract and sexually transmitted infection. They can also determine if you are resistant to any of the antibiotics you are presently using, this may be a reason for the lack of response. I hope this helps
