urinary tract infection
"I began to take Macrobid (Nitrofurantoin mono) 100mg caplets on last Thursday for a UTI.   Within 24 hours I had severe muscle aching, headache, and fatigue.  Within 2 days I had even more severe body aches, joint pain, extreme fatigue and sleepiness, dizziness and difficulty walking as well as a fever of 101-102 degrees.  I went in to a walk in clinic but symptoms progressed and by Sunday I was in the ER thinking I was in septic shock.  I assumed my infection had spread, I had no idea it could be a reaction to the antibiotic.  After a barrage of tests including a CT scan, the only possibility is that this poison was wrecking my health.   This medication caused me a huge amount of problems.  I stopped taking it yesterday and still have a headache, dizziness, muscle aches and low fever.  I can only hope the damage caused by Macrobid is not permanent."
