In 2012 with our strange S CA weather this winter, I have had constant sinus congestion/swelling, post nasal drip,
nose bleeds after trying a different prescription antihistamine spray and it seems saline rinses and daily Claritin offer no relief.
I will also add..About 10 months, I got a referral to an ENT who did a very brief exam of my nasal passages and ordered sinus x-rays.They came back normal.
