Could the botox have caused a sinus infection? Did she freeze my sinuses?

I can't see any way in which Botox would cause a sinus infection. Continue to see your doctor until the coincidental sinus infection resolves.The information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.  The information provided should not be relied upon as a substitute for consultations with a qualified health professional who may be familiar with your individual medical needs. 

It’s unlikely that your sinus infection was caused by Botox and most likely a coincidence. I recommend following up with your primary care doctor or even ear nose and throat doctor about your sinus infection.  I recommend a formal consultation with a reputable and experienced cosmetic dermatologist to help you get the results you want.

Botox only acts locally on the muscles into which it was injected.  The sinuses are all bony covered and Botox does not penetrate the bone.  The sinuses of the cheek, between the eyes and forehead are all very deep and protected by the hard bony skeleton, so I think that your sinus problems are just a coincidence.  I would recommend being seen by an ENT doctor to further evaluate and work up your sinusitis.

Botox does  not cause sinus infections. You need to see your primary care physician for an evaluation for possible sinus infection.

Thank you for your question. Botox has not been directly linked to causing sinus infections, especially when injected with sterile technique and with proper skin prep prior to the injection. The sinus cavities are deeper than the dermis muscle where Botox is injected and should not be affected by the injection. Botox works primarily by blocking nerve impulses to certain muscles, not by 'freezing' them (in the usual sense). The information provided in Dr. Richardson's answer is for educational purposes only and is not intended to constitute medical advice.

It is unlikely that Botox had any relation to your sinus or tooth infections.  It is probably just a coincidence.

It is highly unlikely that your Botox injection had anything to do with your sinus infection. I would highly recommend seeing your primary care physician until it resolves. Hope you feel better

Sorry to hear about your troubles.Based on your description it seems unlikely that the Botox injection would have anything to do with your tooth and sinus issues.

It is highly unlikely that your Botox treatment would cause a sinus infection. It is probably more of a coincidence in timing. We suggest starting with a visit to your family doctor and if they feel differently than follow up with your Botox provider.
