Is my vision being affected because I was hit in the area I got Botox in?

Question

I have Botox near my smile lines and on my brow bone I was hit in my smile line region & my brow bone region. This is several weeks after injection, the Botox is firmly still in my face and I currently have a concussion. Some of the symptoms of concussion can be blurred vision because of headaches I don’t know if it’s the headaches that are causing the blurred vision or bc I was hit in the area I got Botox in. Can being hit in the head in the area you got Botox in affect your vision

Being hit to the head can affect vision, but having had Botox injected several weeks before the hit should not have any influence on vision.

I'm sorry to hear of the injury you sustained.  Your Botox treatment is completely unrelated to your symptoms.  I encourage you to visit with your primary care physician for follow up.

Thank you for your question sabrinamalikkkk. I understand your concern. Botox is a purified protein used to address wrinkles associated with facial expression. When injected into the skin Botox will relax the muscles and smoothen out the overlying wrinkles. The most common areas of treatment are in the upper face. These include the horizontal lines seen on the upper forehead when one raises the brows, the vertical lines seen between the brows when one frowns (frown lines), and the crow's feet seen around the eyes when one smiles.
It is difficult to make an assessment without a formal exam in the office where I can view the skin in multiple angles and observe wrinkles formed with facial expression. However, I hope the information provided here is useful.The pivotal studies used 24 units of Botox (12 units per side) to address the crow’s feet. These studies demonstrated that the peak results are seen 14 days after the treatment and most people enjoy their results for 3-4 months. At that point, a maintenance treatment is recommended. While some people start to see results as early as the next day, it can take two weeks for full results so patience is important. We have our patients return two weeks after their treatment to assess their results via photographs. At that time additional units may be added if necessary. 
If I had a patient with the concern described here I would say that blurred vision can definitely happen after being hit in the head, especially if it was strong enough to cause a concussion. However, I would say that it is unrelated to Botox.With any injection, there are risks such as pain, bleeding, bruising, redness, swelling, tenderness, and infection. We take special precautions to minimize these risks such as using a painless technique. We also treat bruises with a laser as early as the next day. Bruises usually resolve within two weeks if untreated. After a laser treatment bruises usually resolve in 1-3 days, but may still take two weeks for full resolution. In addition to these risks, with Botox there is also a risk that the product spreads or diffuses to nearby structures. Spread to nearby muscles can lead to side effects such as the temporary appearance of droopy eyelids or a temporary asymmetric smile.
  
After a Botox treatment, I recommend that my patients avoid heat exposure, alcohol consumption, and strenuous exercise for 24 hours and not lie down flat for four hours. This is because all of these activities may possibly lead to the movement of the product and consequent side effects such as droopy eyelids. Although there have been no definitive studies shown that these actually occur and some physicians do not provide such aftercare instructions, in the absence of data I err on the side of caution and recommend that my patients avoid such activities.
  
Please consult with a doctor for specific recommendations. Good luck!
