I've been suffering from flu like symptoms for three days now. I'm struggling to do much, I've a headache, sore throat, sneezing a lot, but nose isn't really bunged up, coughing and have a crackly chest, I'm really achy and I'm roasting one minute and freezing the next. My appetite is ok though, just reduced. I suffer from an auto immune condition and get colds fairly frequently; this is considerably worse than any I've experienced recently. Stupidly I've not yet had the flu vaccine. Could this be what it is? And if so, should I contact the GP? Don't think I can go there just now but I doubt they'll come out as they're so busy.
