I took my first covaxin yesterday and had major issues after 30-40 minutes Like increased heart rate, dizzy ,nausea , breathing difficulty to the extent that I felt I would faint. Symptoms have improved after sometime and later. Since then I feel there's a heavy feeling in my chest But above all my blood pressure has increased since then ,I just checked it was 137/86 now It's never been like this What to do? Is it normal post vaccination or should I do something about it . especially my blood pressure I'm 23 I've never had this issue
