Headaches and Trouble Swallowing After Botox Injection

A mild headache and eyelid droopiness can occur after this procedure. However, trouble swallowing is a concern. Please see your injector asap.

Headaches are not uncommon after Botulinum Toxin (Botox and Dysport) injections and are generally short lived. There are some experimental data to shown that the Botulinum Toxin (Botox and Dysport) can travel backwards (retrograde transport) from the nerve to the central nervous system where theoretically it could effect the brain but this is a stretch of the imagination. and does not appear to be true in general practice.It also could theoretically travel via the blood stream but this is also unlikely as the cause of your problems.
 

You certainly can develop a headache from botox injection but swallowing problems are unusual if injected into the forehead. Contact you doctor.

It's not unusual to have a slight headache after BOTOX but at 4 days after your treatment, it shouldn't be persistent.  Also, having botox to your frown lines should not cause trouble swallowing or blurry vision.  I'd recommend you go to your internist to make sure you aren't missing something.  He may also want to send you to an eye doctor.
