    Dear Dr, I was diagnosed with laryngitis and severe flu with fever when I went to urgent care. They prescribed Tami flu and cough syrup with codeine. I've taken vitamins, tea, etc and rest. It's been over a week and my sore throat and cough are still not gone but I can talk better, but today I threw up and had the runs at the same time. And I'm sweaty. What's going on? Is this my body healing? Thanks

      Hello Dizzy. I wonder if you might have picked up another infection. Fighting the original flu does weaken the immune system and you are more prone to picking up another infection, sometimes termed a 'complication'. This might be either a bacterial or viral infection. If your symptoms do not improve within 24 hours, you should seek further advice from your local doctor.

    Dear Dr, I've had night sweats the last 3 nights were my clothes and bedding are saturated waking up every hour so not even getting a refreshing nights sleep. During the day I feel cold and have been dosing up on lemsip and iboprufen how do these symptoms usually last? Thanks

      Hello R. Night sweats caused by flu rarely last beyond a few days. What you describe suggests a severe infection and assuming that this started as an upper respiratory viral illness, you may also have picked up a bacterial complication along the way. If your symptoms do not start to improve in the next 24 hours, I would suggest you seek further help from your local doctors to rule out other reasons for your symptoms.

    I recently was diagnosed with epilepsy at the age of 70. For the past two nights I have had a horrible headache right above my eyes and along my forehead. I have become dizzy and confused but I have not had seizures. I feel that after reading the flu symptoms I may be developing the flu. Is this a possibility or is it more signs of epilepsy? Presently, I am taking lamotrigine. In the past 6 months I have had two seizures; the last one was the result of immense stress, poor eating, and poor sleep. The first one was the result of nose surgery. Both “seizures” lasted less then 2 minutes

      Hello Mike. Yes, a viral infection affecting your sinuses could be the cause, but this will not be the first thought on my mind taking into account your medical history. I wonder if you might have a migraine - this condition can be associated with epilepsy. In any case, your symptoms are not typical and I would suggest that you make an appointment to see your doctor in order to get to the bottom of your headache.
