In brief: Depends
Vast majority of the people have no side effects, other than minor soreness at the site.
If you are allergic to something in the vaccine, you could have local swelling redness, pain, itching etc and in rare cases a life threatening anaphylactic reaction. There may be the usual effects of a needle stick. It is important to mention all your allergies to the person giving the shot.

In brief: Potential effects
Flu shot side effects may include: slight swelling, redness or pain at vaccination site.
If headache, nausea, fever or muscular pain occur they usually resolve within one to two days. You won't get the flu from a flu shot because the virus either contains inactivated virus or doesn't have virus particles in it. Severe side effects are rare.
