Wow, I just read your post on a journal from 2008 about your daughter having very similar symptoms to me with regards to her 1.1cm pineal cyst. You asked me if I breathe through my mouth a lot...YES! In fact, that was one of the strange things that happened to me around that time--my nasal passages swelled up and they've never really opened up since. I always breathe through my mouth and at least half of the time I'm really congested (I just had a nasty sinus infection for all of the month of March '10). I haven't been able to convince a doctor to really consider the pineal cyst as the cause of all of this, yet. How is your daughter doing? Have doctors been monitoring her pineal cyst? Please let me know how she's doing! -Julia
