constant headaches, nausea, fatigue, vertigo, chest pain

Had my first dose of Pfizer 31.08.21 and second dose 21.10.21.

Since having the vaccine I have had severe headaches constantly, migraines which ive never had, nausea, insane fatigue, dizzy spells, vertigo and started having intense chest pain a few days ago (09.12.21). I have seen a doctor and had my bloods checked and recieved a b12 injection and I am b12 deficient however it hasn’t improved and is only getting worse. Nothing else in my life leads me to believe it could be something other than vaccine side effects.
