Can local anesthesia cause headaches?

After local anesthesia, I have bad headaches. Will they go away soon?

A side effect from local anesthetic toxicity could include nervous system involvement like headaches, but this would require excessive amounts of local anesthesia to be used and is very unlikely.
No.
Hi,

Headache after the use of a local anesthetic is rare, but may happen, and it will go away. The incidence of headache may vary with the location of application of the local anesthetic and the amount used. And the duration of the headache also will vary according to the site of application and the amount used.

With best wishes,

There are many types of headaches and many potential causes of headaches, but local anesthetics have NEVER been shown to cause them. All numbing and other effects of local anesthetics disappear completely after 24 hours. Go see a headache specialist.
No
Local anesthesia would not cause headache. It is spinal anesthesia that can cause headache.
