Excessive saliva and excessive coughing

[ScubaGirl74]

My husband fell head first into a concrete barrier. The C1 was fractured in three places and he had a severe concussion concussion. Since then he’s had excessive saliva resulting in excessive coughing. He’s coughing several times a minute.
Is there any connection between brain trauma and excessive saliva?

Probably. If he never had this before and he does now, you can at least speculate there is a connection. What does his doctor say?

Excess consciousness of saliva and of swallowing can also be a psychological response to something, kind of a cousin of OCD, even if it's a psychological response to actual trauma. But if he's actually having to cough a lot, clearly there is more saliva than there used to be, going through his pipes. So I wouldn't let his doc blow it off by saying it's all in his head.
