A lot of CH'ers are experiencing a higher than normal frequency of their CH this time of year and that includes a few of us on the anti-inflammatory regimen who are also experiencing some burn through hits.
There's a high probability this increase in CH activity is due to the spring pollen causing allergic reactions that flood our systems with histamines. When that happens nearly every form of CH intervention is less effective or not effective at all.
The insidious thing about pollen allergies is they can be sub-clinical with no outward symptoms so you could be having an allergic reaction and never know it. Pollen can also lay around the house, car and workplace for months.
All it takes is a little movement to send the pollen airborne and it hits the nasal passages. When that happens, mast cells in the mucus membranes start dumping histamines into the local area and bloodstream. When the histamines reach the trigeminal ganglia, they trigger neurogenic inflammation and we're off to the races with another bout of CH.
There are other sources of allergens that are with us year round. Any damp areas can generate mold spores and the biggest source is dust mites. They live with us year round in bedding and pillows... They may not be enough to trigger an allergic response on their own, but throw in a little more spring pollen and you reach a tipping point where there's enough to trigger an allergic response.
Here's my story... I'm a chronic type and have kept my CH in full remission with the anti-inflammatory regimen (10,000 IU/day vitamin D3, Omega-3 fish oil and all the vitamin D3 cofactors: magnesium, zinc, boron, vitamin A (reinol) and the vitamin K2 complex MK4 and MK7).
I live in the Puget Sound area of NW Washington state. I started falling out of remission in mid March as soon as I returned from a stay with friends down in Key West, FL where I had been CH pain free taking 15,000 IU/day vitamin D3.
Alder tree pollen was sifting out of the mature trees that surround our house like a dust storm that coated my black pickup turning it gray with a very sticky and heavy dusting that acts like powdered weldwood glue when the rains hit it. See photo below.

It took less than 24 hours after I returned home for allergy symptoms to appear and that was when I had the first outbreak of CH. I realized what was happening so started taking vitamin D3 at 50,000 IU/day as loading doses thinking that would overpower the flood of histamine triggered by the pollen allergy. A week of loading cut the frequency a little but not completely. I was still getting hit one or two times a night while sleeping
At that point the clue bird made a low pass and the good idea light came on bright... Treat the allergy!
It took a little reading to identify the best treatment option and I finally settled on benedryl (diphenhydramine), a first-generation antihistamine. I started taking it as directed at 25 mg four times a day, every 4 to 6 hours... It took a day for the benedryl to start working, but by the second day I was back in a CH pain free state...
The rationale for benedryl is it passes through the blood brain barrier to block histamine receptors in brain cells. Benedryl doesn't stop the mast cells from releasing histamine and other cytokines, but it does help block the allergic reaction and associated inflammation.
The only downside of benedryl is it acts as a CNS depressant so I've been a bit drowsy and napping frequently... Second- and third-generation antihistamines can't get past the blood brain barrier so don't pose a problem with drowsiness, but as they can't pass through the blood brain barrier, they would likely be ineffective in this case.
It's been a month and so far so good. The Alder pollen drop is over, but it's been replaced by an equally heavy pollen drop from the Bigleaf Maple trees...

We've several 200 year old Bigleaf Maple trees near the house and they're loaded with blooms that drop a yellow pollen that collects on my pickup like finely ground cornmeal.
I've managed to cut back on the vitamin D3 to 25,000 IU/day and three benedryl tabs/24 hours... and still remain pain free... Lesson learned!
Hope this helps...
Take care,
