Further Update
Spoke with the doc about another issue (documentation) and she just said that my episode was due a cardio problem that could occur in anyone and kind of "one of those things."
All good to hear.
Gingernut, I posted on here a few months back about persistent headaches and causes and received some interesting responses. The fact is, and wasn't feeling this at the time and have spoken with the doc previously about this, I have a one sided headache that keeps coming back from time to time. Was told by the doc that it was sinus related and she gave me olba oil plus amoxycillin which SEEMED to do the trick but it keeps coming back from time to time. Didn't have it yesterday but woke up feeling it this morning - not agonising at all but painful and VERY annoying. It started about 6 months agao when I had a "viral infection" - severe cough and then the headaches came - was told initially it was the strain of the coughs and then told a sinus infection. I know there are about 200 possibilities but value your opinion.
Cheers
