Hi. You are probaby suffering the side-effects of removal. Did you get them removed with all precautions? This can make a difference. But it is common to get problems for a while after removal.

Do you know if you are allergic to something? I think allergic reactions can cause the throat to "close" - that' s just my thought, but it may be worth getting things checked out. If doctor's can't find a cause, then that might be an indication it's mercury.
