I am sorry to hear that you have been unwell.
I see that you have posted your question from one of our flu pages. Yes, flu can give rise to a variety of symptoms including tiredness, muscle and joint pains.
These should resolve as the infection subsides. To help recovery, we would recommend a combination of Echinacea and sage in the form of a hot drink.
I trust that this is of some help to you.
