Is fresh air CFAIR medical device physiological seawater nasal spray irritating to nasal mucosa?
There is no adverse reaction, but attention should be paid to nasal cavity injury. Don't use it or cross it. Breathing is really smooth after using it. They have isotonic and hypertonic sprays at home. I suggest you consult their customer service first, and give professional advice according to your situation. You can accept my suggestion and continue to ask questions if you don't understand.
