That's great Pippa! So, do you go back to see him in 4 weeks time? It must be really reassuring to have had someone tell you it's okay and although it feels bad and distracting, you're not going to collapse or anything...
How does he know that your blood pressure comes down soon afterwards? Are you measuring it at home? I feel like mine is constantly too high. My fingers feel tight, a bit like rubber gloves blown up a bit... my feet and ankles feel trembly and twitchy and I feel like there is something on my back or across my back, some constant pressure. When it eases, it is sooooo calming and relaxing and I think 'wow, this is how I used to feel all the time....'. I don't think the heat helps either, I'm sure being hot increases your blood pressure and it was really hot today.
The GP today tried the 'it could be white coat syndrome' thing, but I was like.... mmmm .... nope. And anyway, if you look at the blood pressure I had taken just before I went onto HRT, it was literally perfect - and that was at a doctor's. I have come to recognise what it 'feels like' to have high blood pressure now...
It is interesting he has seen so many women on HRT with this. But I'm not sure he's got to the root cause of it.
I reckon Scampidoodle's histamine intolerance idea is still very interesting. I know I tried a low histamine diet and it didn't do anything, but if I have all my life teetered on just about being okay with histamine - and then I add in extra estrogen, including going up to quite high doses of patch - when my ovaries perhaps have also started to make my own... well perhaps just eating low histamine wouldn't have made much difference at that point. It was just a drop in the ocean. And now I've had quite a flare up through staying on it and maybe mast cells have gotten involved, who knows.
I am going to increase my vitamin c doses to 4x daily (natural anti-histamine), take DAO before eating (since I bought it anyway and then never used it!), keep going with the quercetin 2x daily, take the L-glutamine I bought but keep forgetting to use... but I can't do the low histamine diet again, I just can't

Maybe I will if all that lot doesn't work...
If I have to go back onto HRT because I get peri symptoms coming back - and at some point I will need HRT - I will try to see if I can see Tina Peers or someone in her meno business who can try to help me do that alongside trying to keep histamine low and maybe some mast cell stabilisers. I probably will only be able to have a very low level of estrogen, but it's got to be better than nothing. I also think something I can take in the morning - estrogel or Lenzetto - which will hopefully wear off slightly come the middle of the night, is a good idea too - rather than patches. If histamine peaks at night, and a patch gives you estrogen 24/7 constantly, that's probably not a good combo.
It might not be histamine, but if it isn't that, I'm stumped for any explanation whatsoever - and I have to work on the basis of something...
