I used to live in a damp basement apartment and reckon my fungal sinusitis all started there. I was never the same since this time and for years I suffered (mostly in silence) with the infection as everything seemed geared towards bacterial infections. I used the sinsuoother natural nose spray and after sneezing up/blowing out clumps of mucous and what looked like fungus I was completely cured and have been ever since. That was around ten months ago.
