Thank you all for your advice on my issue. Well, the spot is really not pain but just a really strong sensation of energy between my eyebrows. I have this sensation ever since I was a seven years old kid. Whenever I focus my thoughts on my forehead I get the feel for it. I don't know how is it beneficial or dangerous for me. I was told by a buddhist nun I should keep an energy spot too long in one place. It will causes cancer or some other unwanted results.
