UTI is not necessarily an STI.

Thanks Saga. I also researched so.

UTI is absolutely not an STI...

Urinary Tract Infections (UTIs) are unusual in men given the anatomy of their genitourinary system. Hence a UTI in a man is always classified as a complicated UTI and must be treated. Uncomplicated UTIs need not be treated, for example a young woman with bacteria in her urine but otherwise no symptoms such as burning with urination, suprapubic tenderness does not need antibiotics.

It is likely that the antibiotic you were treated with did not have adequate coverage for the type of bacteria causing your infection. It is very important that you get a urine culture with sensitivities to guide treatment. Untreated UTIs can progress to severe kidney infection. Moreover since you're a man you will need to be evaluated by a specialist for any signs of structural abnormalities. Lastly, talk to your doctor about using pyridium (phenazopyridine)for symptomatic relief of burning with urination. Pyridium causes an orange discoloration of your urine, which is just a benign side effect that you should not worry about.

please get him proper consultancy. he is still young & by the looks of things it might affect his kidneys & you can imagine what that means.
