Thank you for your service @fattestfoot . I would advise you and @CursedEyeball to consider registering with the World Trade Center Health Program if you had exposure to the disaster area in downtown NYC between 9/11/01 and 05/02. I know too many people who have suffered from all types of illnesses related to their exposure to the dust cloud and burn pits. @CursedEyeball described the acrid air that blanketed that area for 9 months post-9/11 so well.
It's still unclear to me why Cluster Headaches have not yet been added to the Zadroga 9/11 Health Act so that people can get the help that they need. I'll continue to research and post here if I make any headway.
