I've always had low blood pressure (100/70 ish)although ironically I got pre-eclampsia with pg. 2 years ago... Since I got back to normal (which took 6 months post-birth) I've had the same bp, but more recently (for 2 months?) I've been more around 100/60-65. I know this might not be useful, but thought I'd mention. - I've only got a bp monitor and been taking it because of pg. experience. I don't usually take it!
Since returning from a charity trek in the desert (v.hard work, but came back not particularly wiped) I've been feeling dizzy/faint quite often, although this was mostly straight after my return, and I thought was dehydration.
for the last 10 days I've been woken by a really splitting headache early in the morning - 5am ish - which just will not quit, until I've taken prescriptions painkillers (diclofenac) left over from lower back problem last year....
Today it's barely gone - but of course I can't take anything else. Seemed to have a focal point behind the eye for a couple of hours at lunch...
First time at the PC, but thought one of you will know something helpful!
PS Had a few migraines as a teenager, doesn't really feel like that - well not like my experience of it anyway.
Sorry, long post!
