Sharp Pain After Botox on Forehead

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.
