Hi, I am 18 year old female,since last 5-6 months i've been feeling irritation between my eyebrows. Its like when you close your eyes and hold a pointed pencil between your eyebrows. It is strain but it happens any time not only when i am concentrating and once it starts it doesn't end for hours doesn't even let me sleep. Its like i have to pinch there or hold that part for it to stop but as i remove my.hand it starts again there are no other feelings like nausea or vomiting accompanying just that feeling and i dont work on computer much but i do read alot. This is very disturbing please help me out...!!
