Are night sweats common after the flu? I had flu symptoms - fever, aches, chills, headache and cough for four days. Last night my fever finally subsided and was 99.1 at 8pm. I was and am still battling, a now worse, cough (now terrible chest cold), but thankfully fever is gone. I woke up four times drenched in sweat, flipping my pillows and moving to a diff section of the bed. The 4th I had to get up and change the sheets and pillows. I've had the flu, but it's been years. I must say, I don't recall ever experiencing anything like this afterwards. Is this normal? How many nights could this potentially last? Thank you!
