Hello!
Welcome on HCM!
Regarding your concern, I would explain that
cervical spine trauma can lead to chronic headache, especially in the back of your head. This is caused by the muscle spasms in the neck, which extend to the back of the head.
It can also lead to irritation of the occipital nerve, which lies in this region, causing this type of headache.
But, a long time has passed from the accident and you should feel better now.
As your troubles persist, I would recommend consulting with a
neurologist for a physical exam and a cervical spine
CT scan or MRI. You may need to hold a
cervical collar if evidence of cervical disk protrusion are revealed in these tests.
If this test result normal, you should consider post-
concussion headache as a possible cause underlying your troubles. In such case, an antidepressant would help relieve your symptoms.
Hope you will find this answer helpful!
Kind regards, Dr. Aida
