I am now fully diagnosed  'Severe chonic cluster headache, Chronic migraine and co-morbid restless legs syndrome'.

Yesterday my consultant injected a 'nerve blocker' into the back of my head to try to deal with the migaines I suffer.  Unfortunately I forgot to ask how long before it works.  I was woken at 5am with a really severe one.  Is this normal?  I expected an immediate relief.  Before the treatment I had a really annoying back headache which, miraculously disappeared soon after the treatment! 

Initially I am also to be prescribed oxygen with sumitriptan injections to cope with the severe CH attacks and if all else fails Verapamil.

It appears I am going to be kept busy this summer.... (Yeh, we do get one in England you skeptics.) ....most annoying because we had to cut our last break short due to a worsening in my condition. 

Hi Bob
Thanks for your reply. 
Since this mornings attack I have had no back headache so, fingers crossed, I might have a bit of a break.  I have looked at other postings on the GONB (nerve block) and there appears to be mixed reactions, it'll be good to be headache free for a while as some have experince of.
I am worried about the oxygen eg size of tanks/equipment etc.  My consultant Dr Siver is arranging it.  The problem is we don't have a car to transport it when visiting distant relatives or staying on our narrowboat.  We are toally reliant on public tansport.  How does this work? Am I going to have to give up holidays and visiting family approximately 300+miles away? The narrowboat is 2 hours away by train. Will they allow me to take oxygen on a train/bus/ boat???

So many questions no time during consultant appointment.

Verapamil was only mentioned at the end of my appointment so not really any explanation of how and what with.

Thanks again Bob.

I'm also puzzled by having both oxygen and Imitrex. Besides the problems of  travel, while O2 is effective, its duration of effect is brief compared to other abortives. Traveling with the Imitrex injection resolves the problem and I don't grasp why the doc advises having two abortives, in any case.

Verapamil is simply the most widely used preventive; safe, effective, pill form. Suggest you press the doc on why you are not using it now. Prevention is the goal, not always having to use an abortive. (Print the PDF file, below, both to educate yourself and as a MEDICAL "tool" to guide discussions with the doc.)

Hi kelt5
I don't know how you would get on with the narrowboat, or public transport. But my oxygen is delivered by a company called DOLBY VIVISOL and they will deliver to any address in the UK if I give them about 3 weeks notice, which is great for visiting relatives.
