The same day, both the hives and the angioedema went away and did not come back. A few days later, on December 29, I had a high
fever (102°F / 39°C) and diarrhea. I went to the emergency room, they made an ecography on my belly and a complete blood count. The doctor said the CBC was totally fine, but the ecography revealed gastroenteritis. She gave me paracetamol, ciprofloxacin and bismuth pectin.
