Hello everyone. I have sinusitis and yesterday they did a lavage with a needle on me. Today I talked to my mother-in-law and she scared me that it was not necessary to do a puncture, now it will repeat itself and repeat itself, you will have to do lavage with a needle all your life, now you can't drink cold water, in summer sit in the room where the air conditioner works and eat ice cream and etc... Who had a puncture, share your experience, is everything so scary?
