Your antibiotics were quite strong, is there any chance you have been battling yeast
infections caused by them? This is quite common, and a yeast infection
can cause burning and discomfort as well and antibiotics can make it worse. Do you have access to over-the-counter pyriduim and cranberry capsules or juice? The pyriduim numbs the urinary tract (and turns your urine an alarming orange color), and the cranberry coats your urinary tract, making it harder for the bacteria to grow.
