Hi there, I felt perfectly fine until one day at work as I suddenly became very hot and dizzy until the point where I almost fainted. After this episode I was fine, however the next day I had a horrible headache , was very weak and ached everywhere! Again, I was very dizzy and tired. The next day my throat started hurting and my ears began hurting and making a squelching sound when I gulp. My throat aches and is sore and now a chesty cough has formed. Is like a typical viral infection?
