question: my 6 year old daughter has tested positive for strep twice now and is on her 2nd round of antibiotics, she has complained of severe abdominal pain and is now having nosebleeds. She had been complaining of the abdominal pain before this 2nd round of antibiotics, but now has the nosebleeds. At the start of this she had sudden onset of abd. pain, with fever , vomiting, grey skin color, heart rate was in the 160 s. We went to the ER for this and she was started on the 2nd antibiotic there through IV, and responded well to this. I am still confused over the abdominal pain and nosebleeds.
