Hi, 
But developed headache here and there and quite frequently.
Since you have not mentioned any symptoms related to nose I think that your problem is related to the brain or so.
I would advise you the following in such a situation: 
Consult your PRimary Physician first and thus get a clinical evaluation and examination done to see for the cause.
IGet primary investigations and may be 
MRI of the brain and relevant investigations of blood.
Primary treatment may help you.
If not then, get an opinion of a 
Neurologist to get further cause sorted and get treated accordingly.
If you find any instigating or enhancing factors then notice these and avid all these including the 
stress and 
anxiety.
Hope I have answered your query. Let me know if I can assist you further. 
Regards, 
Dr. T Chandrakant, General Surgeon
