B Allen,
Thanks for the update... and good questions... For starters, 11 days of vitamin D3 at 50,000 IU/day is a healthy total loading dose of 550,000 IU of vitamin D3.
If your starting 25(OH)D was 53 ng/mL, then your present 25(OH)D serum concentration should be around 110 ng/mL based on an average response to dose of vitamin D3.
Accordingly, it's a good idea to drop the daily vitamin D3 intake to a maintenance dose of 10,000 IU/day. I'd also stop the calcium supplements for a week or so until the vitamin D3 is actively preventing your CH. Stopping calcium supplements has helped a few CH'er improve their response to vitamin D3.
A serum concentration of 25(OH)D of 110 ng/mL is not a concern. I've had several CH'ers take their serum 25(OH)D up to 190 ng/mL while under a physician's supervision with frequent labs for serum 25(OH)D, calcium and PTH (Parathyroid Hormone) with no problems noted.
There are a couple possible reasons why you haven't responded by now... The first is the present anti-inflammatory regimen suggests a 3-month course of vitamin B 50 to address any possible deficiencies among the seven B vitamins.
The second and likely more probable reason why you haven't responded is you're likely experiencing an allergic reaction to tree pollen (allergic rhinitis). Some allergy symptoms are obvious... stuffy sinus, eyes feel like they have dust in them, puffy face... Other allergies may be sub-clinical, i.e., no outward or obvious symptoms...
In either case, allergic reactions trigger the release of histamine and that results in a generalized inflammation that can affect the trigeminal ganglia and rest of the brain for that matter... If you face is a little puffy and sinuses a little stuffy, imagine what the brain looks like...
I encountered this problem in early March when the Alder and Bigleaf Maple pollen was blowing around like a dust storm around the yard. My black pickup looked like it had been dusted with a bag of Portland Cement.

I'd been away on travel for nearly two weeks and return on the 9th of March to find my pickup in the above condition... I knew this was going to be a problem so upped my vitamin D3 intake to 50,000 IU/day...
Within 12 hours of returning home, the allergy symptoms were obvious... 24 hours later, I fell out of CH remission... I'm chronic and normally keep my 25(OH)D between 80 and 100 ng/mL... so thought the vitamin D3 loading dose would help.
Nearly a week later with no change in my CH pattern of 3 hits a night, the clue bird made a low pass and my "Good Idea" light came on bright and flashing... "Treat The Allergy !!!"
The treatment solution was Benadryl (Diphenhydraming). Benadryl is a first-generation antihistamine that passes through the blood brain barrier to block histamine receptors. It takes roughly 3 hours to reach a maximum serum concentration and its half-life in adults is 10 to 12 hours...
That makes two (2) 25 mg tablets a day, one in the A.M. and one 12 hours later a good dose. Benadryl is also a mild CNS depressant at this dose and it will make you drowsy so try not to drive if at all possible. If you do need to drive to work and back, take a single 25 mg Benadryl tablet when you're home for the night... Drowsiness shouldn't be a problem the next morning.
Within 12 hours after starting the Benadryl I experienced a significant decrease in allergy symptoms.. 24 hours later, the frequency of my CH hits had dropped to one minor hit. By 48 hours after starting the Benadryl, I was again completely CH pain free so I dropped my vitamin D3 intake to 20,000 IU/day.
If you stop and think about it... it's difficult for a molecule of Benadryl to block a histamine receptor if that receptor is already occupied by histamine... That makes it important to maintain a constant serum concentration of Benadryl by taking a 25 mg tablet every 12 hours...
I've since tapered my vitamin D3 intake back down to a maintenance dose of 10,000 IU/day. However, as there's still some spring pollen floating around in the yard, I still need at least one 25 mg tablet of Benadryl to stay CH pain free.
I keep the following link updated with the latest changes to the anti-inflammatory regimen:
