Free text: Since day two after 1st dose have had vertigo. First day of vertigo was moderate. Vertigo still there but lessening each day. Have had vertigo and balance issues before. Have neurological/ nerve issues since bad fall and concussion 2 years ago. Unsure if that is a contributing factor to what I feel is a reaction to the vaccine?
