I have burning sensation on fore head what do i do?

Hard to say: May be due to various causes. It would be more helpful if you give more information: How long has it been present? Does it last all day? If not, how long each time. Where in the forehead: in the center vs on either side of forehead? Are there any other symptoms: fever, trouble with vision or any other symptoms? "Burning" type pain often signifies a problem with a local nerve to the involved area.
