Hello,
I've been sick with what seems like a cold for about a week. Very congested in the head / sinuses, fatty cough (spitting up flem frequently), and general pain (especially in the head).
What can I do to get better quickly?

ALSO-- I don't know how it happens nor how long it's been, but every time I brush my teeth I realize that my inner bottom lip burns and is very sore, along with my labial frenulum, which seems torn and burns a lot... What could this be??

Thank you for your help!
