My 5 yr old son has been unwell on and of for a few weeks now he only has slight temperature of 37.5 but feels hotter to touch he is very pale and lethargic and he is shivering saying he is cold he also is complaining of a bad head??? a few weeks ago he had a chest infection was put on antibiotics which he has had before and towards the end of the course he suddenly started being sick and complaining of sharp abdominal pain we took him doctors and he said he may have abdominal colic caused by the coughing and sent us home!!! I don t believe this . He was sick again when we got home then slept all night the following day he woke up feeling and looking better and went to school he was there 1 day and then was off for 2 days being sick again with bad belly . He then went back and has been back 1 wk and 3 days and is now being sick again with bad headache and leg cramps very pale he is not overly keen on the light but can sit in room with it on I am very worried about this as usually he is a healthy 5 yr old apart from asthma !!! Please help Oh also my husbands friend tht he worked with was taken to hospital just before all this started and died meningitis in 72 hrs my husband was checked but was given the all clear with a tablet but I think it a little coincidental!!thank u a very worried mummy

Hi welcome to Chat Doctor ... Your child having fever on and off along with abdominal pain sometime... Here if generalized viral infection there than chest and stomach both can be affected. Your child work up needed with.... -Auscultation -Blood pressure measurement -Chest x-ray if needed-CRP -Blood culture if needed -USG abdomen According to cause further treatment can be guided.... If no significant cause found than just maintain immunity with good food and fruits. Advise :Pediatrician consultation for examination. Take care
