Don't want to sound like a broken record here. But you really do need to see a doctor. To find out if you have a UTI ( urinery track infection ) Just a long name for a bladder infection. The doctor will just have you give them a sample and they check it really quick to see if there is an infection. Takes just a couple of minutes. But if you don't get it treated as soon as you can, it can cause big problems.
Good Luck and I hope you feel better soon, Monty
