33year old. First botox 7 weeks ago. 11 units in the typical v pattern in glabella region. 1 week ago muscle over my right brow began to involuntarily contract. released after 10 seconds. Now both of my eyebrows will spontaneously take on my old furroewd mad brow look. Happens several times a day. Massage will actually make it happen- not alleviate it. Possibility of nerve damage by needles or muscle trauma...? Looking for any plausible diagnosis and any other symptoms that might accompany.
Involuntary Brow Contraction?

Muscle Movement after Botox
The muscles in the glabellar region may need an adjustment in dose or frequency of Botox administered.

You likely need more Botox, and the area that is trying to contract involuntarily are your muscles starting to work again. Next treatment, discuss with your provider and determine whether or not increasing the dose might resolve your issue.
Botox and muscle spasms
There is no reason to worry about any damage due to the botox. You probably just need more. My guess is that the untreated muscles are trying now moving more or with less opposition due to the botox in the treated muscles. A little dose in these areas should help that.

The muscles that control "frown line" contraction are actually more than the ones that it sounds like were treated with 11 units. To treat this area it typically can take between 20-40 units (depending on the patients muscle tone, needs, and discretion of the injecting physician). This is usually spread over 3-6 injection sites on the forehead. It sounds like the frontalis muscle may not have been treated or was not injected with enough units of product. This muscle can appear to push inward to create your furrow (against the frozen treated muscles). The movement can occur when you are not trying to frown, a facial expression that may involve the frontalis. Evaluation by your injecting MD is recommended to see if additional treatment is needed.
Involuntary brow contraction after Botox
11 units is a veeerrrrry small amount, first of all. Usually when people state they have "muscle spasms" after Botox it's because untreated muscles are working harder to counter the effects of the muscles that aren't working as hard, due to the Botox. This would be what's happening in your case. The muscles that can move and work are doing so. There is no nerve or muscle damage. It's simply muscles that can move, are moving. Your options would be to treat these muscles in addition next time, or to not get Botox. Because clearly you have muscles that tend to work very hard (ultimately, these types of muscles will cause a more permanent etching of lines into the forehead and glabella if they are allowed to move), you need more Botox and in additional areas to stop this.
