Thank you for your query at DoctorSpring.com
I understand your concern.
Can you give me detaled medical history? Do you have any previous history of UTI?
Directly there is no reason to attribute it to diabetes or renal failure since there will be other symptoms present along with it. Sometimes we have increased frequency of urination, and depending on fluid intake the color of urine can also vary. Can be considered a part of physiological variation.
A little tingling that you referred to can indicate a recent UTI.
Feel free to discuss further,
