Have been using Symbicort and Spiriva Respimat for COPD for a few years. I always feel my throat is coated and swallowing is not difficult but uncomfortable. I have tried gargling with salt water but doesn’t help. I do rinse and gargle after using my inhalers. A pharmacist said nasal drip is common when using inhalers so I’ve tried Nasacort, no help. I don’t have trouble breathing through my nose. Any suggestions would be greatly appreciated
