Hi, my granddaughter, 5 years old, suffered a very bad Uti last week and went to hospital on Friday. She was given antibiotics and a shot. She was ill for 4 days leading up to the diagnosis, but her only complaint was stomach pain, within 5 minutes of eating anything. She began complaining of stomach pain again yesterday, and was retested her urine is fine now. But she just broke out in hives from head to toe and is on her way back to the ER. Any thoughts?
