I've had high BP at times - but only when measured in the GP surgery! I bought a BP measury thing on Amazon (about 25 quid) and was delighted that I am normal
It's really well worth doing.
Also re the BP issues. Don't use mouthwash! There have been various studies shown that it has a detrimental effect on BP.
I also drank a lot of beetroot juice which is supposed to be excellent for BP.
For the irregular heart beats, I take Magnesium - cholated mag, which I read somewhere was absorbed better? It really helps with the palpitations.
I did have an ECG and a 24 hour monitor just to make sure I wasn't about to peg it, (and to reassure me really) and I was fine, so I think these are all just hormonal symptoms. (I used to get palpitations the day before my period - not sure how this ties in hormonally??? During my 3rd pregnancy I was hospitalised with a crazy heartbeat so I'm sure I"m just prone to these things. I was on beta blockers for a good year, which worked but made me feel pretty numb and cold)
I've also experienced weird little electric shocks which are quite nasty, and made me think I was about to have a stroke.
I really hope your symptoms subside, christinedownsouth x
