Has anyone seen fever and night sweats for three days after forehead Botox?

Thank you for your question.  I have never heard of fever from botox injections.  If it persists, I would see your primary care Dr. for evaluation.  

While the dental implant could be the cause of your symptoms, the fact that this was one week after the implant makes this a bit unlikely. On the other hand, Botox can cause flu-like symptoms and this includes low-grade fever and increased sweating at night. The fact that your CBC was normal makes me think that your oral surgeon was correct. However, you also took Clindamycin. Your symptoms could also have been a reaction to this antibiotic. Clindamycin can cause numerous side effects including dangerous ones such as inflammatory bowel disease, bloody diarrhea and death. The most reasonable answer for me is Botox. If you check out Botox side effects, you will find that flu-like symptoms are listed among the common side-effects of Botox. This makes the other two possibilities much less likely.
