Is it safe to be traveling after a burr hole and craniotomy?

Depends. If everything is healed up and there have been no neurological sequelae, it should be fine. If the neurological status has returned to normal and there are no problems with wound healing and there are no problems with seizures, it is not uncommon for people to travel. Obviously, they should travel with friends/family who are available to help.Probably shouldn't drive until released by neurosurgeon.
