It wouldn't hurt to call your doc and request a stool screen just in case. But yes, the symptoms are quite similar.
Symptoms began in November 2008, ~4 weeks after giving birth to my son.
Eased for ~3 weeks in December, possibly b/c of probiotic use?
Returned in January 2009 (with a vengeance), diagnosed with pancolitis on January 30.
Currently taking Asacol (400mg 4 pills 3x daily), Rowasa nightly, 40mg of Prednisone (quick taper), Culturelle probiotic, and Zoloft (25 mg).
