Had Annual Flu Vaccine 10 Days Ago. Since Then I

Had annual flu vaccine 10 days ago. since then I have experienced significant eye discomfort in the form of pressure, pulsating, burning sensation. no redness or swelling. localized pain between eyes along brow bridge that is very sensitive to touch. Plus low level headache. I'm assuming this is side effect to vaccine. If so, how long should this last. If not, what else could it be.
