**im from australia** so i had my second dose of pfizer on monday 11th october, i instantly got a headache, the next day i had a headache, body aches, chills and i felt abit dizzy… it is now saturday and i’m still really dizzy and experiencing diarrhoea and vomiting aswell as stomach cramps.. my doctor seems to think it’s from the covid vaccine and it’ll go away on its own and another doctor seems to think i’ve been struck with gastro on top as side effects
