<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 5 year old son has a fever of 103.3. Gave tyanol and it only brought it to 102.3 last night he had horrible leg pain and if you touched his legs he screamed. He s now saying his forehead hurts. He s also has been coughing too. Should I bring him to the ER. I m really worried  <response>: Hi...this seems to be a viral illness with myositis or inflammation of muscles. If your kid is normal in between fever episodes in a single day... I dont think you should worry as its only 3rd day of fever. Danger signs include breathlessness rash low urine output seizures unconsciousness blood in motion. Dont worry if these are not there the kid is active. Hope my answer was helpful for you. Happy to help anytime. Further clarifications and consultations on Chat Doctor are welcome.
