Treatment advice abroad

Hi there - newbie here!

I was diagnosed with CH around 2 years ago but by the time I got the diagnosis from a neurologist, my cycle had ended and I received Samantriptan tablets in case it came on again. Fast-forward two CH-free years and it's back with a vegence but, this time, I am working in South Sudan. 

I have been trying to bear it for the last two weeks being unable to work and in excrutiating pain - dashing to the nearest clinic for oxygen when it gets unbearable. They perscribed me Sandomigran as it was the only thing slightly close to what I needed but it does nothing for me ...perhaps even enlongates an attack (I might be making that up).

To cut a long story short, it has all become too much and tomorrow I am flying to Nairobi to see a neurologist at the Aga Khan University Hospital and wanted to ask for some advice if the Dr is not up to speed on CH. I know that the hospital does not have the Samantriptan injection pens (I checked with them) that I was hoping for so was wondering if anybody had any advice at all about any other effective meds? 

My last cycle lasted for about 2/3 weeks so was hoping this might be simmilar but it seems different this time and it twice a day. As I am based in the middle of nowhere in South Sudan, I really hope to get some releif before I head back.

Thank you in advance.
