Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain, the symptoms of Throat feeling closed, hard to breath, red throat, coughing, itchy throat and always happening after eating Broccoli can be most probably due to
Allergy to Broccoli..
It comes under
food allergies..
But for confirmation you need to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like Food Challenge test,
RAST test can help in confirmation of the cause..
In case if broccoli allergy is confirmed as the cause then the best way to avoid the reaction is to avoid eating broccoli..
In case if you are accidentally exposed to the allergen then you can take anti allergics like Levocetrizine or
Allegra..
You can also be instilled an
Immunotherapy that will help in reducing the severity and frequency of allergic attack..

Hope this information helps..
Thanks and regards.
