Hi, After being sick for most of November (flu-like symptoms that came and went over the month), for the last week, I have been feeling nauseous, dizzy, and extremely tired in the evenings. My head feel "heavy" and my eyesight has been blurry (I wear contacts). For awhile I thought it was just another symptom of being sick but now I no longer cough or have chest congestion so I am a bit worried. Thanks!
