Re: Can a food allergy cause nasal pressure?
It is very complicated, but allergies can play a large part in triggering the inflammation in the sinus and nasal passages. I have had allergies to cats/pollen/dust/trees/mould/housedust mite etc all my life and usually react with wheezing, itching, sneezing and at its worst..asthma.. But I have managed to control my allergies with antihystamines. And haven't had asthma for 15 years now...but I still continued to take loratadine/ceterizine routinely. I'm now on what you would know as Allegra (Fexofenadine)
So my sinusitis has been put down to allergies....has my body suddenly changed after 40 years to deal with allergies? Quite possibly, but maybe a different allergy...possibly food allergy. I know I developed an intolerance to white processed bread 8 years ago as it made me feel nauseous (but have been ok with wholemeal). But your body can change and react differently.
Dairy/soya/gluten/sugar/alcohol are all supposed to make sinusitis worse...it's hard to determine where or how to start eliminating everything from your diet.
My problem is I'm attacking my sinusitis from every angle, so going to be difficult to pinpoint the real cause if I succeed in beating this infection.
Also trying to find the right antibiotic is tricky (doctors in UK don't tend to do cultures to identify correct antibiotic....they just give amoxicillin for 7-10 days as standard and then infection comes straight back after a few days of temporary respite).
Though after reading about peroxide solution flooding, I'm now beginning to undestand the cycle of re-infection! So that's why I'm now on a 2 week course of Doxycycline AND 2-3 times daily sinus flooding with either very dilute peroxide/saline/bicarb or colloidal silver/saline/bicarb (colloidal silver seems to be less aggressive but I'm not sure how effective these are at the concentrations I'm using!)
