Hi I am a mom of 2 girls, 13 days ago I came down with a fever and chest cold, stayed in bed then my 12 year old caught it, then my husband milder than ours...never became fully well when this week we all 4 came down with sweaty, stomach nausea, headache, shaky, mild sore throat. We are all exhausted and it is all very non descript. Can't figure out what it could be...any thoughts? PS No fever this week but sweaty then chills.
