I also get chronic UTI's and have to take macrobid on a regular basis..its a pain because after awhile you get yeast infections from build up of antibiotics..so have to take something to help keep those away too.
One thing that will help you tremendously..run a warm bath and soak and let yourself pee every time you need to..sounds gross..I know..but trust me, it helps! They will not go away on their own, you have to have antibiotic..I also am at the doc office the minute one comes on...I can tell before I ever get to the gotta pee every few minutes stage..can feel it in my lower back..blood in the urine is common..infact its there even if YOU cant see it with an infection..they are not going to put you in the hospital UNLESS you go untreated and it turns into a Kidney infection and then you are putting yourself in big danger..so get treated!! And feel better!
