Thank you for posting your query.
First of all, I want to reassure you that the headache is most likely not related to tumour
Also, the tumors in NF1 are benign and they are almost never cancerous.
The tumour in the neck may give rise to neck pain
, but not headache.
In your case, the most likely cause of headache is stress
I hope it clarifies.
Wishing you good health,
