Hi, Kristin, sorry to hear you are under the weather. I hope you feel better very soon!
I had fever and digestive upsets for a long time after returning home. Except for identifying a duodenol ulcer we never did figure out what I had but I had every scan, biopsy, and test possible and you all know what that means. Treatment involved antibiotics (I hate using antibiotics so you know I was miserable if I agreed to take them) and probiotics (Probiosyn and Biotisyn) and a liquid diet as needed to manage symptoms.
More than six months later I am finally feeling quite a bit better and grateful for it! The ER doc diagnosed a parasite but my regular doc didn't agree. She thought the incubation period wasn't right and the symptoms weren't right either. So we don't know what it was and it took a few shots in the dark but I'm finally on the mend. I trust your path to healing will be a little more straightforward!
