Dear Doc,3 1/2 years ago I had a deviated septum w/ allergies, had an operation and life was awesome for 6months. After the 6months it felt back to square one, Im allergic to dust and grass, Nasonex helps slightly (I can breathe through 60% of my nostril) and fexofenadine stops my eyes from being super sore, but Im so desperate to get the same feeling I had after the operation, occasionally I do have days of bliss, Id say once every couple months (doing nothing differently), Is it worth going back and having the operation again, even though I know full well its going to come back? I have read about this injection being made in Switzerland, a cure for all allergies, but 4 years is a long time! Looking forward to any help you can provide,Regards,PoP.S. Ive tried everything, on prescription and a neti pot, can work for 2-3 days but nothing for me as of yet (apart from the op) has been a long term fix.

Hello, Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions for you as follows:1. It is important to remember that sinus surgery corrects structural problems related to nose/sinuses, it cannot "cure" allergies as basically, allergies are related to immune system. So, unless your ENT surgeon suggests you need to have a repeated surgery (he will advise you only after examination of inside your nose and after some investigations), you may not actually require a surgery.2. Were I treating you, I would suggest you to continue intranasal corticosteroids (alone), I would add regular montelukast and an antihistamine like fexofenadine, cetirizine or levocetirizine.3. I would suggest you regular steam inhalation (please be cautious to avoid burns) and net. It will help.4. Should you have reflux symptoms, i.e., regurgitation of foods after meals or burning pain in chest, especially after hot/spicy/oily meals, I would prescribe you antacid like omeprazole for at least 6 weeks? It can worsen sinusitis.5. I would also suggest you allergy testing and consult an Allergist-Immunologist with the report. After reviewing your symptoms and reports, he may prescribe you allergen specific immunotherapy. The "injections" you have heard of might be actually immunotherapy. Nowadays, there are both injections and Chat Doctor. Of course, it should be continued for 3-5 years, but improvement in symptoms usually begins within first 6 months of beginning of immunotherapy. It works on your immune system to modify response towards the substances one is allergic to and hence improves allergies gradually.6. A diet rich in vitamins and minerals as well as avoidance of dusts, smokes and air pollution will also help you. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you the best of the health. Thank you & Regards.
