Yes, I 've had a flare after eating just one forbidden food. For now, like Gachrons suggested, keep an eye on your temperature. Drink ( or try) lots of fluids , get plenty of rest and if in 2 days or so you are not better, see your doctor or head to the ER. If you have any strictures, something could have become lodged or stuck. So sorry you are going thru all this. Good luck to you. '
Love and prayers,'
