The alternative is allergy, which is clearly what your doc suspects.
He must have kept it to himself!
There are nasal sprays as well as drops but as with all steroids the indvidual response is unpredicable so you may need to try several before finding success (fluticasone proprionate may be worth mentioning to GP - beware over use can cause thining of the nasal walls and lead to nse bleeds).
We tried a couple, including a strong one, and they were totally useless. My ME doc wanted me to stop them because steroids suppress the immune system.
Some of the sinus medications contain vaso constrictors, these cause the lining of the sinus connection to the soft palette at the back of the nose, to open. This connection is a tiny tube a few millimetres in length and about a millimetre wide (head of pin), the blocking of this by thickened mucus, produced in response to either infection or allergen produces pain.
That's interesting - it sounds like extremely poor design!
Combining treatments can help - vasoconstrictors, astringents - like Karvol or Olbas Oil - and steroids, can be more effective than using them singly.
I've used vasoconstrictors in the past but they wear off after a few days, and I've tried peppermint oil, olbas oil, etc. which don't do anything - and I've got to stay off the steroids.
Look to reduce allergen exposure - pollen, dust, scented laundry products etc. It may be worth wearing a surgical/diy mask when cleaning, vacuuming etc, as well as taking a general anti allergen like Fexofenadine - this can lead to drowsines though, but is helpful for sleep.
I'm pretty much housebound so don't get much pollen exposure and I get these headaches year-round. I don't use scented stuff and don't do any housework (I hire a helper and leave the room while she's cleaning). I'll ask my ME doc about Fexofenadine - I wish I could get to the cause of this thing rather than treating the symptoms, though, especially since I'm worried about any of these drugs interacting with other stuff.
Using nasal flushes can have unwanted consequences, changing the microbiome of the nose can actualy promote infection and inflamation, while the initial problem in the sinus is actually untouched, so you get a double problem that then becomes circular.
That's interesting. I've become worried about that since I learned about the microbiome. I sent a nasal swab off to uBiome a couple of months ago and am waiting for the result. If I've stuffed up my nasal microbiome, I don't know what to do about it. Argh!
Sorry, I think this is a bit of a negative reply to your response! I think my headache is making me a bit contrary!
