I moved to the South and now have nasal congestion, sinus clog, and asthma. I have taken 4 allergy tests(2 prick tests, 2 blood tests). All are negative. Why did this just occur when I moved and what besides these ineffective nose sprays can I use for relief?
Hello, Welcome to Chat Doctor, The symptoms are suggesting me that you are having some allergic reaction which is causing all these symptoms. Nasal congestion and sinus clog are due to release of mediators of allergy like histamine which is responsible for your symptoms. As you have tested yourself with different allergen and found negative to allergens, I would suggest you to test for absolute eosinophil count to confirm the presence of allergic reaction in the body. For the present symptoms I would suggest you to take medicine like Tab Least, thrice daily for 5 days which will improve the conditions and makes you feel better. Thank you.
