I have been experiencing for the past week symptoms including low fever (100-101), headaches, fatigue. Low appetite. Falling asleep easily, malaise, chills, restlessness, depression, difficult bowel movements.

It seems to finally go away one day, and then comes back again later on.

I realize of course that this is flu, but I'm wondering what type and how long should I expect it to last.

Thank you.

It is dangerous to diagnose over the Internet - you should see a Physician.
