Apologies for hijacking your thread a little bit, but...
Loose Rivets; can you elaborate on your salt water remedy please? Are you just suggesting gargle salt water?
I'm struggling at present with seemingly incurable sinusitis (never had it before) going back almost nine months, and am interested in what you've said.
I've been tested for allergies with a negative result, just finished four weeks of antibiotics (can't remember the name, but they make you susceptible to sunburn

) and no change, CT scan showed up as 'normal' but my head/ears/sinusus etc. are anything but 'normal'

. Docs now out of ideas and have asked me to take antihistamines and come back in six weeks; and I thought we'd ruled out allergies

.
Any advice or straws I can clutch on to much appreciated.
