Hey Vince,
When oxygen therapy was my only method of controlling CH, I traveled all over the US, Hawaii, Alaska as well as across Europe, the UK and Norway...
I traveled with my own regulator, non-rebreathing oxygen mask and oxygen demand valve throughout the US. I always had oxygen waiting at my destination. I even had an adapter made to enable me to use my oxygen demand valve in Germany and Switzerland... Different standards in different countries.
Flying with your own oxygen system or one provided by the airlines is an expensive crap shoot and not worth the trouble or expense IMHO. An imitrex nasal spray or two usually covers most cross country flights...
Airgas should have a travel program for most US locations... If they don't, Oxytravel does... All they need is a copy of your Rx for oxygen.
For local travel in my car and at work, I kept an M60 with regulator and mask in my trunk...
As it appears you've a great neurologist and friend, ask for the lab test for 25(OH)D. This is the serum level metabolite of vitamin D3 that's used to measure its status. The normal reference range is 30 to 100 ng/mL.
Nearly every CH'er with active CH who has gone in for this lab test has had the results come back as deficient, < 30 ng/mL.
Better than 80% of CH'ers who have started the anti-inflammatory regimen with at least 10,000 IU/day vitamin D3 plus Omega-3 fish oil, and the rest of the vitamin D3 cofactors has experienced a significant reduction in the frequency, severity and duration of their CH. 78% experience 24 hour pain free days. Nearly 60% have remained pain free.
This regimen is proving to be effective for both episodic and chronic CH'ers with 83% of episodic CH'ers and 73% of chronic CH'ers experiencing a favorable response.
The latest survey data as of Friday on this regimen indicates when these CH'ers tested their 25(OH)D after the favorable response to this regimen, their average 25(OH)D serum concentration was 78.5 ng/mL, STDV 29.2. I'm still crunching the numbers, but it appears the slight advantage enjoyed by episodic CH'ers may be due to confusing a favorable response to this regimen with end of cycle.
Roughly 500 CH'ers have reported starting this regimen here at CH.com since December of 2010... The raw data harvested from their posts indicate better than 80 % of them have experienced a favorable response...
