Legitamate medical conditions include stress and anxiety. While proving mental anguish is certainly more difficult than proving physical pain in terms of a juror being able to relate, it is no less real. To your second post, yes, putting up a sign would be equal to INCREASING their discomfort, it is no less a freedom of speach or rights of a private property owner. Hell, look at the examples of people flying Nazi/Rebel/Upside down flags (last one is a bad example because of flag laws) but other cases still apply. All I'm saying is, unless you're throwing rocks from your house at your neighbor, you're not responsible if you running your microwave causes their pacemaker to jump.
