flank pain, back pain and stomach pain
For a month or so, I have been having flank (both sides), stomach and lower back pain. It seems to come and go. I am now taking nitrofurantoin (110 mg) for E.coli. Today begins my second day of medication.
Could this pain be from E.coli? I do have gallstones, too, but am told that is a completely different pain in a different area.
