Botox 1 mo ago. My head feels heavy, weird headaches, my eyes are much more hooded now, brows appear pushed down. What can I do?

The frontalis or forehead muscle can be very sensitive to Botox.  It is the ONLY brow elevator muscle in the face.  What that means is that if you receive more Botox in the forehead than you can handle (this is VERY variable and ranges widely), your forehead will be smooth, but your brows will be pushed down and patients describe it as a brow heaviness.  The good thing is that this will wear off as the Botox does in a few weeks to months.  The next time you get injected, I would relay this experience and use less in the forehead and/or inject higher on the forehead.

The injection was too close to the eyebrows and should be at a higher level so this problem doesn't occur. Seek treatment at your local doctor. 

Some of the side effects are due to your injection being too low (too close to the eyebrows) and this may be helped with iopidine eye drops. the headaches etc are unusual but do occur with Botox but will last only a couple of weeks and disappear on their own. see your doctor to get some treatment and be sure you are seeing a board certified dermatologist or plastic surgeon
