Complaining in a irritating way.

Here's some random teka-teki. Random and freaking easy. Guess the disease, people.

Symptoms:
-very cold until it stabs me in the bones
-malaise
-sore-throat
-pallatine tonsils swollen
-armpit's lymph nodes swollen
-my head weighs a ton

Treatments:
-paracetamol/acetomenophen
-Kool Fever on the forehead
-shower with water heater, always (this is my own treatment, the real one is actually opposite and starts with the lower limbs)
-drink plain water soo many many

So, this disease is very common. And the answer is?
