Doc Put 50 Units of Botox In my Face is This Too Much I Got Saggy Eyes, and Migraines

It is not possible to agree or disagree with whether or not 50 units of Botox was appropriate for your treatment without assessing your need prior.  However, generally speaking, 50 units for a female forehead and dosing around the eyes seems a little excessive especially with the negative outcomes that you are describing.

We disagree that headaches are categorically related to poor technique in all cases.  Rather, it's more likely that in your case, dosing (the amount used) caused too much relaxation of the forehead (hence the drooping brows/eyelids) and the forehead muscle is trying to compensate by working harder to animate or lift the brows.  This reaction is avoided by a more conservative dosing to the forehead.

We encourage you to return to your practitioner to be evaluated and to have your concerns adressed.  Most likely, you will find these negative side effects improve with time.

There is no substitute for seeing someone who knows what they are doing.  I personally believe that the headaches are the result of an unbalanced BOTOX treatment.  This causes compensatory muscle recruitment accounting for the muscular strain and headaches.  I would recommend letting this wear off and then either avoiding BOTOX altogether or finding an injecting physician who actually knows what they are doing.
