Hi My son is 14, bad cough, headache, stomache a little queezy, he s feeling shaky and week, also body temp is low. It s been 97.1. 97.4, 97.7, this am it was 95.5, but quickly bounced back up to 96.6 then 97.1. We went to dr s yesterday, they dissmissed low temp., chest and lungs are clear. So they said he just has a bad cold with a cough. The low temp got worse today and the shakiness and leg weekness started this morning. He has a metabolic disorder, but is eating and drinking well. He does usually have a normal body temp. What could this be? Is it just his bodies way of reacting to this particular virus?
