Thanks for your query. You are worrying unnecessarily. Tetanus boosters have been given to millions of people without any significant side effects. Still it has not been proven concretely that thiomersal of tetanus vaccine
has such significant side effects or else it would have been removed from the market. There are agencies which are strictly monitoring the side effects.
If your problem is persisting you need to show it to a physician as the symtoms fit the diagnosis of migraine
and treatment will help.
