Finding an oxygen supplier was half of the battle alone.. But may I recommend locating one, and then speaking with your Neuro about writing a prescription for oxygen? The mask can be bought through clusterbusters.org .. All in all, I think I spent roughly $200 to get up and running with oxygen..
I am still cluster free (roughly 4 or 5 years now).. I still believe that taking the immatrex injections only semi -aborted my clusters. I would feel the beast constantly there, almost like hovering in a dark corner behind me. I had to allow the clusters to break through (very hard to make that conscience decision) and then treat with oxygen (after I had it in my possession of course)..
My very last round of clusters was so incredibly different than the prior years that I swear it added up to me being cluster free now.. I've read that they can and usually do return, but for now I'm enjoying several years of cluster free days.. I quit taking varapamil because it didn't seem to help.. The cancer steroids that they gave me made me gain SO much weight and the immatrex never seemed to make them completely go away.. Do all that you can to find out about oxygen! Even if you can get to the ER to request it, in the middle of an attack (as long as someone drives you!)..
Also, if I may note, I've had boughs of anger and frustration (ugh teenagers are HARD!) that sent me into instant cluster headaches.. My father also has cluster headaches (chronic sufferer) and maybe coincidently, but he also has anger issues much worse than I do.. Something to consider, at the very least, eh?
One other thing! I have one of those thermometers that you put on or near you're forehead to take temperature.. My father was at my house when he went into a cluster headache one morning, and for curiosity sake, I took a reading of his temperature.. Would y'all believe his temperature was near normal on the unaffected side, and very elevated on the cluster side, especially around the ear and neck? I don't know why and I couldn't find any data to support it, but it's true.. I use to self admit myself to the ER every other day during cluster periods. When I could convince them to give me a steroid injection (this was prior to evidence proving steroids worked), it would prevent that nights cluster, along with the following nights cluster (hence going in every other day).. The hospital thought I was a nutcase, but I swear to God it worked (that was in 2010 or 2011 I believe)..
I pray for each and every one of you! 2 of my 3 sons have migraines, so far no signs of cluster headaches. I've never had a migraine to my knowledge.. But the last time my oldest son had a migraine, I had him try the oxygen and it worked to abort the migraine as well
