Best to visit your GP to get a proper diagnosis to see if this is PD or just mental stress which can effect the body and mind in mysterious ways. Anything is possible.
How disturbing for you to have to endure someone else's taste of music and especially loudly, no one should have to put up with that, I think even the sanest of people would not be able to cope. The response from your manager should have been reported to someone higher up the ladder or else an organisation that deals with this sort of work related situation, I'm sure you should never have to have tolerated that, with all the rules and regulations in place.
Take care and hope you get some sort of satisfaction in your plight - Sheffy
