So two days ago I had a really great urge it urinate and not a lot came out. I had a slight burning sensation but nothing bad at all. Yesterday everything was normal, but today the urge to urinate came back. I went to use the bathroom and very little came out, about an hour and a half later the urge came back. When I went to use the bathroom my urine was dark almost as if there was blood in it. I also had a burning sensation. I have had a UTI before and this feels different. Could it be a kidney infection??
