If the injection is done too fast or too deep, excessive swelling and bruising can occur. Bruising is especially common if the injector hits a vein or pushes to hard. While this is a temporary side effect, the patient will be forced to live with an unsightly bruise for days if not weeks.
Answer: Botox hit a nerve
Just as you have described, a nerve was hit along the hairline and feels like an electric sensation when touched. Though very uncommon this can happen with any kind of injection done. While it is painful for a bit, it will resolve on its own in the next week or two and stop hurting.
The frontalis is injected either intramuscularly or superficially just under the subcutaneous tissues. In general, injection is performed at least 1.5 cm above the superior orbital rim to prevent ptosis.
Botox must be injected into the superficial layers of the skin in some areas, while in others, it needs to be injected deeply. One example is the masseter muscle near the mouth. If a practitioner doesn't inject this muscle deeply enough, patients can end up with an uneven or unbalanced smile.
Even the best physicians can cause a patient to bruise after administering BOTOX. It often occurs when the needle knicks a blood vessel, allowing blood to leak below the skin's surface and causing the surface to appear reddish and/or purple.
However, when it is not performed properly, Botox can result in a "frozen" or fake look. The most common causes of botched Botox are: Improper injection techniques. Many unskilled injectors make the mistake of injecting Botox too deeply or too superficially into the skin.
A good injector should know where to never inject.
A qualified, experienced injector should never inject the area near the orbital bone right above the pupil. If Botox is injected here, it can drift down toward the upper eyelid and cause an eyelid droop. This can last from weeks to even months.
When the doctor injects Botox into your forehead, you may hear a crunching sound. This noise occurs because the needle goes through the galea — a fibrous sheet of connective tissue that forms the middle layer of the scalp.
Cannulas have proven to be more effective in decreasing the number of complications, but we do recommend aspirating, considering that with cannulas the injuries can be more severe and harder to treat if the injection was made in a blood vessel.
Too much Botox in the forehead muscles can cause the eyebrows to droop, making the upper eyelids look very heavy and hooded. The face may look angry or sad all the time. Too much Botox around the eyes can dramatically affect facial expression. The face is simply frozen.
If too much Botox was injected and your face doesn't move, you'll just have to wait for it to wear off. Unfortunately, there's no quick fix for this.
Botox can not fill out very deep wrinkles, and will likely not smooth them out completely. In order to completely eradicate deeper lines, you may want to look into filler, or other facial treatments, such as non surgical facelifts, face lifts, thread lifts, and other treatments available.
Other injection site events
If a nerve is hit, the patient will feel an immediate burning pain, which can result in paralysis or neuropathy that does not always resolve.
There are no long-term or life-threatening adverse effects related to botulinum toxin treatment for any cosmetic indications. Moreover, the risk of possible complications can be reduced by means of a thorough analysis of the patient's medical history and the use of the appropriate dose and technique for the injection.
Answer: Botox and nerve symptoms
These cosmetic doses are not associated with nerve symptoms spread throughout the body.
Drooping eyelids
When Botox migrates to either the forehead or the area between the eyes, this can result in a droopy eyelid. One reason people choose Botox may be to reduce the appearance of forehead or vertical frown lines.
This is highly unlikely to be permanent and will likely resolve when the botulinum toxin effect dissapates between 3-5 months.
Some of the lines that you have in the forehead are very deep. Remember, the botox can soften the lines but if someone has a very deep line, it wont completely efface it. 2. It sounds like you didn't have any botox on your forehead and thus should be able to move your forehead up and down.
Botox does have long-term side effects
This can cause indentation in the temple and indentation in the forehead furrow line, which creates a shelf-like droop of wasted muscle.
Botox Injection Mistakes: Where Not to Inject Botox
Injecting the frontalis muscles (the two main forehead muscles above the eyebrows) instead of the corrugator supercilii muscle (smaller muscles around the eyebrows) can cause a “Mephisto Effect” or “Spock brows” — comically arched eyebrows.
The use of high Botox dose usually results in loss of expressions. In some articles and textbooks, the recommended dose of botulinum toxin type A injections is 20-40 Units for the glabella region, 15-30 units for the forehead and 12-30 units for the crow's feet.
When Botox is applied to problem areas around the eyebrows, the muscles relax and the skin on top of them becomes smoother. The muscles around the eyebrows are pulled upwards, elevating the eyebrows and making a patient's eyes appear more open.
Botox onset is 5 to 7 days. Botox peaks at 10 to 14 days.
Botox stays only where injected, it does not roam through the body. "If I inject it in your face, it's not going to work [or show up in] your toe," says Rowe. "It does not have a systemic effect." However, it may migrate up to 3 cm from where it was injected.
