Day 0 My hand starts incredibly hurt when I go to sleep
Day 3 I wake up with insane acne
Day 4 I am insanely tired after work
Day 5 I am just sick
Day 6 I call in sick leave to work
Day 7 My arm pain disappeares as soon as I get over the worst phase of illness.

What the fuck is human body. Did some illness seriously show itself on my hand 4 days before I got sick? Why only left arm? Why wirst? And why didn't the body tell me to prepare sooner then on day 4?
