bladder infection
"65 years old, never had a urinary tract infection before, (now I know what they are!) probably had it for months, related symptoms to nurse friend, she said to call DR., sounds like a UTI. Doctor gave Macrobid prescription, 20 hours later after first couple capsules, had 99% relief.  Continued taking for two weeks and didn't have side effects, as far as I could determine. I won't wait months before calling physician next time."
