Is it normal to feel sick after Botox/filers?

Do you feel ok now? You might need a check up to make sure it isn't something completely separate to the Botox.
Headaches are reasonably common but light headedness is probably quite rare (though still possible).

Thanks for you for question and we always recommend that you have these in the offices of a board certified dermatologist or plastic surgeon – and that in these consultations, you learn all of the potential adverse events or things that happen to many – including headaches. These can persist for several weeks after the procedure, but I am sure you will do fine shortly.
