I have suffered with puffy eyes in the morning since adolescents. My symptoms have worsened over the last few years and my puffy eyes are now visible all day, every day! I was recently told my thyroid is borderline low, so could this be one of the causes? I was also tested for allergies and my test results showed I have a dust allergy! I am desperate to resolve this problem and I am now considering surgery! Is it wise to opt for surgery when I am unsure of the cause for my puffy eyes? I must also mention when I take a flight my symptoms are exasperated, and my eyes are usually red and extremely puffy, I also suffer from swelling in my ankles and legs (during flights) and have done since my late teens (I am now 35 years old). I would appreciate any suggestions regarding my problem.
