Can injections in the cheeks cause headaches?

Generally, fillers in the medial portion of the cheek do not cause headaches.  However, fillers injected near the temples may cause some temporal pain, pain with chewing, and occasionally a slight head ache that usually resolve in a few days.  If pain with fillers worsens or doesn't abate, it is always a good idea to see your physician to be evaluated in person.

It would be unusual for injections in the cheeks to cause headaches. That being said, you may have been anxious about the injections and that can cause headaches.  Best, Dr. Green
