I Have Had A Swollen Face And Neck For Several

I have had a swollen face and neck for several weeks. Different diagnosis...allergy/infection of sinuses. Difficulty swallowing. Coupled with reflux pain at the onset of the swelling. Fed up. Blood tests tonorrow for thyroid. No infection as per previous blood test. I'm thinking it could be an allergy to soy???!!! Any info or knowledge would be helpful. Going for c.t. Scan this week. Thank you.
