Sorry for the typo. I meant I haven't had flu for 10-12 years (not days)
It is true that flu can cause a fever with a rash but usually only in children. Even though influenza rarely causes a skin rash in adults, it isn't impossible for it to happen, especially if the person has a history of skin rashes caused by allergies. On how long the rashes will last, it depends on the types of allergies you have.
Yesss well not like I have kept track all my life of how often or not I get hives. My daughter first got hives when she was about 18mos? Can&#39;t quite remember now but she had broncolitis (doctor diagnosed via x-ray) and told me just to give her plenty of rest and enough water, nutrient senses juices. She had a fever, congestion, lethargic, you know a whole thing. After she was getting better, or at the drop of the last day of that fever, she broke out in hives on her chest, belly, and arms. After this, within a couple days she was back to her usual self. Then, this winter, I came down with a flu, don&#39;t know which one, a flu, with a fever, wet cough, bad headache, etc.... After the fever went down finally after three days of lying in bed (no doctor for me, fought the flu myself with soup and juices, tea), here I am the next day with hives?! Itchy as heck, I also have a post-viral cough, sore throat currently. No more fever or symptoms of flu.
I had an all over body rashes following a bout of Mononucleosis. They were never clear whether it came from the Mono or from the penicillin. As a precaution, I don’t take penicillin. Not sure what or if anything you were given to treat your illness but could be your immune system in overdrive or a reaction to something you took to relieve your symptoms. Good luck... 2 years later lol
