Wow! All these years and all the problems you've had to deal with and nobody ever spotted this major "structural defect." It just goes to show, once again, how shabby the treatment for folks with brain injuries/issues really is. Seriously, if you'd been having chest pain do you think it would have taken this long to discover a missing valve or blocked artery?
Do you have this massive urge to gift wrap your scan and send it to all the doctors who ever dismissed your symptoms as minor or psychological? I loved your joke about the aliens and admire you for being able to keep your sense of humour through all this.
Keep us posted as things move along and know that we are all pulling for you.
Cheers
