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 the symptoms of cold and flu. Supplements like Echinaforce help increase the body’s resistance to infection by strengthening the immune system, allowing the body to fight the misery of colds and flu.

      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.

      Hello Eric. This could be because of a viral infection, but there are many other causes of severe back pain, depending on your age and previous medical history. The best advice I can give you at this point, is to approach your local doctor urgently with the aim of establishing the cause of your pain.
