Hi,
Thanks for writing in.
Given the kind of symptoms you have, I am inclined to think that we are definitely looking at some allergic process, maybe even cough variant asthma. Although the swollen glands indicate an infection, if you did have such a long lasting infection, you would have an extremely poor appetite and would have lost some weight as well. Let me know if this is the case.
As of now, I would suggest the following:
a. Take steam inhalation twice a day. Take a pan of water and boil it for like 15-20 minutes. Thereafter, cover your head and the pan with a huge towel and inhale the vapour.
b. Vacuum your house religiously and keep a wet cloth on your nose while travelling
c. Keep a symptom diary to see when your symptoms get worse.
d. Speak with your physician about inhalers with corticosteroids and beta blockers

However, to help you further, I would need the following information from you:
a. You have mentioned eating disorders in the category. Am I missing something here/
b. Has a spirometry or any blood test been ever done for you?
c. Do you notice your symptoms worsen with exposure to anything? Dust, pigeons, mold, pollen.. anything at all that you might want to mention.

Awaiting your reply
Regards
