Sharp Pain After Botox on Forehead

What you experienced is very rare. The needle most likely hit a small sensory nerve. There is not need to worry. There is no long term effect. The nerve likely has a small bruise on it that will take a few days to heal. In the mean time, you may have some symptoms like you are describing until the swelling has resolved.

From your description a nerve was hit during injection and you have some residual stimulation to this area. It should resolve over the next few days and will not impact your results.

Thank you for your question! Although Botox can cause headaches this is generally considered a rare side effect. The exact cause of Botox headaches is not certain but it is believed that the most likely cause is from over contraction of certain muscles in the face. Botox can definitely cause headaches but in most cases they are mild and short acting. This side effect should resolve within the next few weeks. Best of luck!

Thank you for your question. What you have described is very rare and mostly likely the needle hit a sensory nerve. There is no need to worry as there is no long term effect. The nerve most likely has a small bruise on it and will take some time to heal. I recommend following up with injector for evaluation if this persists. Best of Luck

Sometimes a nerve is hit during an injection of Botox, or there can be a bruise like feeling because the muscle is injected or a blood vessel hit causing mild bruising and swelling that can't necessarily be seen. It would be unusual for this to last more than 1-2 weeks. You may want to try an anti-inflammatory pill to see if that helps or acetaminophen if not contraindicated. ~ Dr. Benjamin Barankin, Toronto Dermatology Centre. 

Dear My,
Of the millions of Botox injections that we perform each year in the field of cosmetic medicine it is a wonder that the scenario that you describe doesn't occur more frequently. At any rate, it is unfortunate that your injector struck a nerve, literally. It does happen and the nerve is bruised and traumatized when it does. It may take several weeks for the symptoms to resolve, but they will. Try not to further traumatize the area with "running the injection site". Good luck!

It is likely that when your doctor injected the Botox, the needle traumatized a larger cutaneous nerve. This is more likely to occur with deeper injections. You are not likely to have any long term effects but the increased nerve sensitivity can last for several weeks.
I hope you are reassured.
