Loose rivets, you have been fortunate to have seen an NHS ENT consultant whom I am sure will give a superior opinion to anyone on here who cant even examine you. Why dont you ask her what the problem is? If you are not happy, ask for a second opinion., but please remember like any doctor that consultant may need to try several remedies over a period of time. Try to build a rapport with her and I am sure you will get excellent care and hopefully some improvement.
