Hello Jorge, I have experienced similar symptoms as you back in 2013. My dr put me on a medication called 'Singulair', generic name is Montelukast. This was a real life changer for me as I was sensitive to just about everything. It works by blocking the receptors in your nasal passages and probably other areas as well. It blocks the allergens from attaching to your receptors. Maybe you can ask your dr about that. Your throat issues sound like it could be acid reflux. I had that and it was very painful as my stomach acid was coming up my throat at night and eating away my esophagus. I started taking ometprazole an hour before each meal and that helped a lot. I only had to be on that for several months. I then followed the protcol for acid reflux such as: don't eat or drink anything for three hours before bedtime, (except for a few sips of water). Sleep with your head and shoulders elevated so that gravity keeps your stomach acid in your stomach. Avoid acidic foods that may burn your fragile esophagus, i.e. cokacola soda, tomatoe sauce and juice, citric juices like lemonade and orange juice, and alcohol. Prednisone is a good drug to combat inflammation, but does not arrest allergies. I hope my suggestions help you in some way. Will you return here and let me know how you are doing? -Terri
