Hi Firegirl,
So sorry to hear about the problems you are currently having! I really hope your appointment went well and that you are feeling better now!
I have Syncope also and was diagnosed with POTS (quite a long name but it's Postural orthostatic tachycardia syndrome). It's a condition where your heart beats a lot faster than normal and reduces your blood pressure at the same time. I collapse on adverage 20-25 times a day and it's really scary especially when out in public. I have had to pack in School and am now home tutored because of it. My Doctor told me POTS can be common in Chronic Pain patients so that might be something to look into for you.
My mum and I are attending a Conference here in the UK a week on Sunday all about Syncope and POTS. All of the leading countries doctors in that area are there so it should be really informative so i'll let you know how it goes.
Best wishes,
Alison x
