Can You Have Delayed Side Effects of Botox? (photo)

Hi dclark.  It would be unusual for the side effects you are noting to show up 6 days after Botox injections.  Typically if you are going to have a bruise or headache it happens at the time of the injection or very shortly thereafter, usually within hours.  

It's possible that the symptoms are unrelated and if they are concerning to you we would suggest visiting your personal physician.

Headaches 6 days after Botox are a bit unusual but certainly nothing to be concerned about.  Most people notice them in the first 24-48 hours.  These are usually relieve easily with any analgesic such as Aleve or Motrin. A few patients of mine claim they notice a slight headache in the muscles treated with Botox until the Botox effect is fully in place, so you should be about there.
