Flu symptoms

What are the symptoms of flu, how long do they last and when should I see a doctor?

Echinacea is a traditional herb known to aid the body in its fight against colds and flu by supporting the immune system – but not all Echinacea is the same! Research shows that the fresher the herb, the more effective the remedy will be, which is why our Echinaforce cold and flu remedies are made using freshly harvested Echinacea.

    I started having extreme full body pain for about 4 days before my scratchy throat started and the next morning I woke with sore throat and fever chills which lasted all of yesterday and found myself in a puddle of sweat this morning. Also the only congestion I have is when I spit. I keep finding streaks of blood in it. Can you help me understand why and how much longer this should last? No fever this morning

      Hello Anjelica. Viral infections such as the cold or flu will trigger an immune response in your body which produces a large number of chemicals in order to fight the infection. These lead to the symptoms typical of these infections. Fever is a common response to infection and sweating is your body's normal response to raised body temperature. The acute stages of flu should resolve within 3 to 5 days but if they persist, you should seek further help from your doctor.

      Hello Robin, A fever is part of the immune system’s natural defence against viral infections, rest as much as possible, as this will encourage your temperature to regulate. Also ensure that you are not becoming dehydrated, as you will lose a lot of water through sweating with a fever. If symptoms persist or worsen, it is a good idea to let the doctor know. Best wishes.

    Hi Doctor, Have had flu symptoms for the last four days now with bad headaches and now runny nose etc. Can you explain to me why and what is the cause of my eyes hurting so much when I look in the corner of my eyes?

      Hello Jeffrey. You might have developed a degree of sinus infection or inflammation - this could account for the headaches described. In addition, there is a sinus situation above each eye and this could explain the pain around the eyes described. A nasal decongestant could help you but you may need a course of antibiotics so if symptoms do not improve in the next day or so, please see your local doctor for further advice.
