urinary tract infection
"I was diagnosed with a UTI and kidney infections.  They started me on Macrobid two days ago and yes,  death on a doornail set in.  When your body utilizes this drug to flush your system,  it doesn't just run to your bladder and ta da!  Your body handles this infection with all it's defenses so you SHOULD expect to feel really icky for about a week.  

I am floored at today's rush in society to get everything done right now or right away.  Every body needs time to heal and recover.  Allow yourself the precious gift of rest and recuperating it needs and unless you begin to spike fever or experience allergic reaction,  hang in there and know it's okay to take some time off to nurture you."
