i tried taking cough syrup, and tylenol for my headaches. My condition seems to get better but then i feel worse. I have headaches, i m dizzy, i get chills but i am really warm, i have phlegm in my throat and every time i try to cough the outer left side of my throat hurts the most and the phlegm doesn t seem to e going away. My throat feels more swollen than the right side, and i have been drinking lots of fluids and taking naps.
