Captain CH...you had a very difficult day and you survived, you are still around reading this. So this excruciating pain is not going to kill you. Nor is the nasal sprays that you have concerns of, providing you don;t take more than prescribed.
RE: Your situation at work today...i've been there, done that on more than 1 occasion, and it is horrific every time, I 100% empathize and would not wish it on anybody even my worst enemy.
Losing dignity is definitely a burden on its own. The embarrassment of colleagues talking about you, printing fingers, whispers behind your back, coming up to you and asking questions of what happened yesterday, etc is something you will have to stay strong dealing with.
The letter to employer is helpful that briefly explains what you are going through, might want to print and pass it out, might not, obviously a personal choice at your discretion.
You mentioned you can't wait to get O2, what are you waiting on a doctors appt in 2 weeks? Please understand that the O2 you will find relief from and the imitrex nasal sprays that you have a limited supply of are both abortive treatments. You truly need a transitional treatment to provide temporary relief while your preventative med is in the slow process (2 weeks or so on average) of becoming effective.
FYI....welders O2 can be purchased without a script. You can also purchase a high demand valve and non-rebreather mask without a prescription.
Obtaining proper treatment for O2 from a doctor may be a challenge and there is a detailed outline on this website of how to obtain a prescription for O2. Do yourself a favor and pay extra attention to detail of what is written as 1 missing link may be the difference of your pain level and impact your overall treatment/remedy.
i.e. You must use a non-rebreather mask, not anything else.
You must have the ability to hyperventilate which can only be done with high flow valve.
You should stay on the O2 for 5 minutes sometime longer after you abort the attack. Etc., etc.
It also will be untimely to wait 2 weeks as you wrote for a doctors appt, followed by a wait for insurance authorization and then a wait for O2 vendor availability/delivery, so you may consider this alternative way (welders O2) to obtain treatment on your own fast (same day/next day) without all the red tape.
Beside the Imitrex nasal sprays you have...ice packs, a bag of frozen peas, energy drinks such as RedBull or Monster (1000 MG of Taurine mixed with caffeine) might each/all help you with relief. But your cycle will most likely drag on for several weeks and being hit everyday can be minimized and possibly eliminated by an effective treatment plan with preventative therapy.
RE: Your most recent posting today, I understand you were venting and rightfully so, as this is the place where others truly understand your living nightmare, but truly want to be of assistance for you so I will ask again....
1. Have you started the natural regimen that many CH'ers here have reported success? If you haven't read it yet, read the post titled "123 days..."
2. Have you started a transitional med and/or preventative med? If so, what are you taking and at what dosages?
Your doctor visit may be 2 weeks away, but keep in mind that there are plenty of resources available on this site, current and archived topics, plus the ability to PM and email others and also post/reply.
