Dennis,

Ask your doctor for a lab test of your 25-Hydroxyvitamin D, a.k.a. 25(OH)D levels.  This is the serum level metabolite of vitamin D3.  You're likely vitamin D3 deficient.  That's a safe bet as most of us are deficient in vitamin D3 unless we take supplements.  We just don't get enough UVB from direct sunlight.

The "normal" reference range for the serum concentration of 25(OH)D is 30-100 ng/mL.  However, all the CH'ers with active CH, who have gone in for this lab test, have had their results come back as deficient or ≥42 ng/mL.

Moreover, CH'ers who have taken the anti-inflammatory regimen with 10,000 IU/day vitamin D3 and gone pain free or had a significant reduction in the frequency and severity of their CH... and then gone in for this lab test, have all had the results come back at ≥60 ng/mL.

The efficacy of this regimen is holding steady with around 70% of the CH'ers who try it experiencing a favorable response...  It also appears to be equally effective for both ECH and CCH types.

If your doctor agrees to this lab test, tell him you'll want to supplement with vitamin D3 at 10,000 IU/day.  If he pitches a hissy fit, make sure you take along a printed copy of the attached study by Garland et al.  It suggests a daily intake of 10,000 IU/day and the abstract concludes with the following statement:  "Universal intake of up to 40,000 IU vitamin D per day is unlikely to result in vitamin D toxicity."

You've already received suggestion on the second thing to ask for...  an Rx for oxygen therapy.  Ask that the Rx be written for an oxygen flow rate of 25 liters/minute, but be prepared for push-back so settle for 15 liters/minute...  You can always get your own regulator capable of higher flow rates...  You'll need a flow rate that supports hyperventilation and that works out to a minimum of 25 liters/minute or better yet, a regulator capable of 40 liters/minute or higher...

I know that may sound like a high flow rate... it isn't.  It's very safe and lots of us use flow rates this high without any problems.

Take care,
