Interesting about the "prescription non-steroidal anti-inflammatory drug that contains diclofenac potassium, used to treat migraine attacks in adults" Cambia.
As is typical, there can be plenty of potential further discussion points contained within a report like yours - I'll just start by zeroing in on the triptans: By your description of them taking up to an hour, it sounds like you could have been prescribed the relatively slow acting pill form? Sumatriptan injections are of course known to be the most effective and much quicker delivery form, plus many get quick enough relief from triptan nasal sprays, but especially if deal killer GI issues aren't encountered with this particular Cambia NSAID, and if its effectiveness continues, it sounds like a much better abortive option for you - congrats on finding such a breakthrough!
Here's hoping there's also an impending breakthrough with your O2 access, since success such as you are finding with a new abortive that is not widely recognized as effective for CH can sometimes be short lived.
