Thanks for writing to XXXXXXX
You have headache from 6 months , the pattern you have described fits into Chronic Tension type headache.
I will describe it to you , see if it fits " It is a chronic head-
pain syndrome characterized by tight, band like discomfort. It is bilateral means on both sides of head. The pain typically builds slowly, fluctuates in severity, and may persist more or less continuously for many days. It may be associated with sleep disturbances."
Classically , it in in whole of head , with a feel of "Band like sensation" like if something is kept on your head.
In case , you have Throbbing ,
photophobia ,
phonophobia ,
nausea or vomitings associated with headache , or if your headache is on one side only (unilateral)
, or if you have any neurological deficit , tell us.
As per your question , you should consult a Physician who is well versed in headache treatment or a
neurologist.
I hope i am able to solve your query , if still you have any query , do ask me.
