Katie,
I would suggest that you contact Frank McCormack, MD who is the Clinical Director of The LAM Foundation. He could give you some advice on how to respond to this and could probably also give you the names of some of some doctors in the UK who could give information or evidence on your behalf.
His e-mail contact information is
frank.mccormack@uc.eduI have been fortunate in not hitting barriers at work. I know that some,especially those who are having noticeable symptoms or problems with LAM have had work problems.
