What to do if I have had my head for 2 days associated with the flu despite the taking of the cold and sinus medication?

Good day, given your fever, it is possible that you are dehydrated and this is worsening your headache. Make sure to drink plenty of water, at least 2 liters per day and even more. Additionally, you could combine two pain relievers, such as Tylenol (acetaminophen) and Advil (ibuprofen). I recommend that you check with your pharmacist which pain reliever is contained in your cold and sinus tablets to avoid exceeding the maximum doses. They can also tell you which analgesic can be combined with these tablets. Note that it is possible that your symptoms will persist for 7 to 10 days. The fever should decrease and completely disappear within the next 72 hours. If this is not the case and your symptoms worsen, I invite you to contact us again or contact info-santé to see if it is necessary to consult a doctor.
