shadows1177,
Is the specialist you have an appt with the end of Feb, a headache specialist/neurologist?
A headache specialist/neurologist is the best specialist to visit regarding CH's, but often an internist or PCP (Primary Care Physician) should be able to prescribe you something to tide you over until your appt the end of Feb.
I wouldn't accept the end of Feb as your only option, unless you enjoy the pain. That was sarcasm, but I am serious too.
Your regular doctor should be able to prescribe Prednisone, Verapamil and Imitrex injections, along with o2.
The only thing you have to lose is your sanity, patience, relationships, marriage, kids?, job?, etc. I, like many, have lost many of these life attributes due to waiting too long, misdiagnosed, trial/error of meds, ignorant doctors, etc.
You truly need to be a self advocate and fight for yourself. Take a look at that cluster quiz again. You really should be able to answer all of the questions, regardless of how new you are to this pain. Share your answers here with us. What questions were you not able to answer?
"Knowledge is power" and this website will educate you to educate others.
Plenty of credible info to print and share with regular doctors, neurologists, employers, ER rooms, insurance co's, etc.
If you wait, odds are against you and most likely your condition will worsen.
If you have CH's, you really need a (1) transitional meds (such as Prednisone), to be started at the same time as you start (2) a preventive med (such as Verapamil) and you will need abortive treatment to control the pain when you get attacked (such as high flow oxygen and Imitrex injections).
You need to arm yourself with knowledge so that you can be your own doctor so to say and tell the doctor...no to tylenol...no to pain pills...no to ineffective dosages of known CH meds that work, etc. Don't settle for anything less than satisfaction. You have medical insurance, call around nearby cities if you have to travel to get to somebody competent.
i.e. I drove 5 hours each way to Mexico just to get Imitrex as I had no insurance and couldn't tolerate the pain.
Unless you do something proactive, you are just setting yourself up for punishment that can be avoided and will only have yourself to blame if you don't take the bull by the balls and run.
Blunt, but truthful.
You mentioned your pain is left sided. Is it always on the left or sometimes on the right or entire head?
Do you feel most pain in/on/and behind your left eye?
Do you feel pain in your left side forehead temple?
Does your left nostril get congested or run?
How long does your pain last?
Have you noticed excruciating pain that wakens you from sleep?
Does your pain (attacks) occur at the exact same time everyday and every night?
These are some of the many CH symptoms/things to share with ANY doctor you hopefully get to ASAP.
Can you lie down when you feel the pain and try to sleep it off or is too unbearable and must pain, scream and cry?
Please do yourself a favor and read, ask questions and vent. Why do I bother writing you all this? Because I care about strangers who also are feeling TORTURE by the DRAGON. I've suffered 32 yrs and have been taken advantage of by doctors, misdiagnosed, guinea pig to meds that were harmful instead of helpful, etc far too long until I educated myself through the help of this website and learned to be a self advocate among an ignorant medical community.
Don't be a stranger!
