Everytime i meditate, i feel a numness in in the third eye region

it starts from the nasal extending along up to the middle of the forehead...It feels just num, as if i have a bag of ice on there... can someone explain why does it feel like this, and it hurts sometimes ... sometimes i can feel back of my eyes, cheek bone areas are all hurting,...

its very intense through meditation and whenever i am conscious of my self....


any idea of whats happening, maybe i am not grounding my self properly or not doing something right, i am unsure?

please help
