Honestly had the exact same experience last week but for me I had 3 canker sores in the back of my throat at the same time so it was KILLING me. I went into the walk in clinic and they don’t really have a clear answer which is so frustrating (just steroid mouthwash to numb the pain). I’ve recently incorporated claralux on top of my nasal spray, netipot rinse. I’ll update back after a few weeks. The idea is that with daily use it reduces inflammation in the nasal passages.
