During a febrile seizure, a kid will usually lose consciousness and tremble wildly with both arms and legs. Eye rolling, inflexible (stiff) limbs, or twitching on only one side or a section of the body, such as an arm or a leg, are less frequent symptoms. There may be vomiting after a febrile seizure. Other symptoms include: • A dull ache in the head when waking up after sleeping through a fever • Changes in behavior or mood during or after a fever • Sore throat, cough, runny nose, earache, stomach pain, or constipation/diarrhea during or after a fever • A red blotchy rash that comes and goes within 24 hours of a fever • Falling down or becoming stiff due to heat exhaustion or stroke • Breathing problems due to lung infection, asthma, or bronchitis • Eating disorders such as anorexia or bulimia • Memory problems such as forgetting things recently learned or events that have happened previously • Confusion about where you are or what day it is
