Is my body giving me warnings to take care of it properly?

Last nite - Bodyaches, feeling damn lousy, sore throat, fever, blocked nose.

This morn - Stomache, so pain until i fainted in the office.

Currently - Headache after a few hrs of tv, and some sort of pain at my right side when i move or sit straight.

Worrying... i know, if the pain get worse i'll go see doc. I hope I'm not so suay... =(
