How can the cause of a cervical disc herniation be addressed?

Lately, I've been using the computer frequently, so my neck has been very stiff, especially when I sleep.

Is my turtle neck getting worse because of this? I'm looking for a solution, so please let me know if massage or anything else can help. ㅜ

When I go to the hospital, I talk about the causes of cervical disc issues so that I don't end up with unnecessary injections and related expenses.

I want to do something that I can consistently maintain and that is effective.

And I heard that changing the pillow can be effective, so I looked into it.

Does a pillow really help with neck disc problems?
