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.

    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.

      Hello Victoria. Headaches can be one of the usual symptoms of flu and may also indicate the development of a sinus infection. This symptoms should resolve as the other symptoms improve. However, if headaches persist or if you find that you are not able tolerate bright lights or have a stiff neck, seek further help from your local doctor.

      Hello Lyndsay. I am sorry to hear that you have been feeling so unwell. Your symptoms might be the result of flu, but I would be expecting you to start recovering by now. As it is not clear what the cause of your symptoms are, and, as you are experiencing severe symptoms, I feel that it would be appropriate to see your doctor just to be on the safe side. I hope you will feel better soon.
