I could not wake up Sat am - all over pain - just exhausted - severe headache. Rested on Sat - slightly more comfortable on Sunday - still awful headache, nausea, all over pain. Monday - could not get up out of bed until 5pm - same thing - exhausted, severe headache, all over pain. No other cold type symptoms - other than chest tightness with a small amount of congestion - better today. Mainly stomach nausea and severe headache. Exhausted, no appetetite, pain all over still. The biggest problem has been unexpected sweats and then chills
