I'm not in ketosis nor is my family. We got flu shots on 12/13. We all had soreness at the shot site. The 15 year old and I had soreness around the shot site right away that lasted a few days (we had soreness from the gym, too); the husband was on a three day delay for the shot site soreness, and did have some muscle aches that we thought were more gym related. No one has complained of headaches. I agree with the extra water suggestion (likely related to being in ketosis) and with the statements around the headache/muscle aches being a normal side effect of a flu shot regardless of ketosis.
If it were to become severe, I would definitely contact your doctor. Although they always ask if you are allergic to eggs, if you are allergic to feathers there is a different shot they will give you. I used to get that one from the allergist, and don't recall any side effects from it. Something to consider for next year.
