My son had a cold about 10 days ago. Ever since finishing his antibiotic , he s had nausea daily, low appetite and just tonight I ve noticed low body temperature of 97.3. He does not show any other symptoms, but should I be concerned that it s meningitis? He takes daily preventative pill/ inhaler to maintain his asthma, so he already has that as a daily symptom as well. The nausea is sporatic and goes away within the hour, so he s continued with his daily routine.
