BP has been fine, he's taken it sitting down and standing up on two of my three appointments and it's been fine, always been fine in the past too so doesn't seem to be that, although that was his suspicion too that maybe my bp dips sometimes. He's said what i am describing is pre-syncope (the bit before a faint) and that maybe it will just go away. I did a load of blood tests today and he's requested a 24hr ECG to check on my heart. It has been improving in that its been less severe - the first week of it i was feeling close to fainting and being sent home from work etc. Recently it's just been a bit of lightheaded spells that pass.
