Hi,
Yes bulging cervical disc can cause headache. I would suggest you to make her undergo some investigative procedures like CT scan and MRI, only then can the final diagnosis be made.
Hi.
Was an MRI or CT scan done which visualized a bulging disc? Are there any other symptoms that your wife experienced.
If a bulging disc is present at the cervical level, it could, in theory, present with symptoms at the back of the head. However, head pressure can be caused by several other disorders aside from a bulging disc.
It would be advisable for her to consult a neurologist to completely assess her condition.
Good luck.
