Me again - Fluey symptoms

[RyanM1994]

Hi All,

Today I have had half a root canal done.
(TOTALLY UNRELATED QUESTION, HOW MUCH ON AVERAGE WOULD THIS COST?)
I have spoken to the dentist and doctor regarding taking antibiotics and regarding my other symptoms.

Since speaking with the health professionals I have developed a blocked nose, sore throat and phlegm (slightly yellow).

Could this be something serious? Could the infection be spreading or anything?
Still waiting for my holiday on saturday, still scared that I'm going to be ill by then.

I haven't eaten or drunk anything today and I feel kinda fluey.

You've probably picked up a cold. We humans get about three per year on average. They're nothing to worry about!

I probably have, I'm just worried that can be a start of a major infection.

Could it be? I'm so sorry
