please i am at my wits end. my son has been ill for several years... started with sever vertigo. that has gone away but now he has a severe popping in his ears, large amounts of nasal discharge recently bloody. he throws up late at night after eating.. now complaining of some hearing loss. we have been to many doctors done mri`s cat scans, muscle therapy etc. all negetive our HMO just told us they are giving up. it would seem to me that after elimenating all those possibilities what remains would be viral or bacterial infection but they refuse to believe it. this is really beginning to affect his mental health after 5 years
