yes it does! (i also suffer from tension headaches & migranes... )
i would sugest just to hang in there, and stay positive.
you could be amazed at what a firm, but plesant request, could get you.
Dont let people get used to steping over you,
make sure they know that they are responsible for their part of the work,
equaly as much as you are.
if they don't respond in a positive way,
maybe it's time to take it over their heads,
use the chain of command.
it will help you. your work. and everyone involved in the matter.
i hope very much that this all works out
