Hi Zoe
Bless you, histamine issues are just the worst. Mine were caused by three bouts of flu, inc H1N1, in the early 2000s, took a long time to figure it out, took many wrong turns (with much bad health advice along the way that made it worse) and it went nuclear at peri (what tipped me over was a general anaesthetic for polyps and a D&C in 2019, then prof Studd put me on whopping amounts of oestrogen and the wheels fell off!). I've been under Dr Tina Peers since 2019, who is an expert in HIT and HRT and menopause, she helped me get stable and tolerate HRT, she's now also an expert in Long Covid (they are essentially the same thing, mast cell over activation, and the trigger can simply just be menopause, or something like a nasty virus. Covid seems to be a particularly horrific one due to it's horrible attack on the ovaries).
I had a quick look at Newsom's factsheet on Long Covid (her factsheet on HIT is very good, but I do know they refer their really tough cases to Tina Peers, I also know they have a reputation on being a bit slap happy with the oestrogen, which again can be disastrous in case where histamine isn't properly stabilised first) but I was surprised to read that her LC document doesn't mention mast cell stabilisers and antihistamnes, and quite worryingly suggests women eat fermented foods like Kimci and Sauerkraut! Fermented foods are the very last thing you should eat if you have histamine problems. I take Symprove for gut, it's made a big difference, but fermented foods nearly put me in hospital (back in the dark days of searching for answers before I was diagnosed with HIT).
I was fortunate I was on protective levels of HRT (alas not continous), and plenty of mast cell calming drugs and supplements when Covid hit - Famotdine in particular is very useful in Covid (it's an antacid, but an H2 antihistamine, worth googling re covid) so I'm hoping I've dodged the worst. I also take Fexofenadine, Montelukast and a tiny bit of Zaditen. I've found Toxaprevent at night (or Enterosgel) is good for pulling histamine out of the gut, and I use a DAO supplement. I do all the vits and minerals. Iron and folic acid has been crucial for me - I am a slow oestrogen metaboliser and I've had to tinker (very carefully) with methylation which has also helped.
I am not in any way dismissing Long Covid - it's been utterly crap - but I do think the name is a bit of a misnomer, it's really Mast Cell Overactivation, which often turns up at peri, or when starting HRT (hayfever, sinus issuse, asthma etc) and sometimes triggered by a virus or an event (there's a trauma component also, so a traumatic birth, a bereavement, a car crash or whatever can kick it off).
There's also a link with anaemia and histamine - and covid crashes iron - I feel a million times better when my iron deficiency is well controlled.
https://www.cambridgeindependent.co.uk/news/long-covid-patient-in-cambridge-tells-how-simple-treatment-t-9203620/The point of me saying all that isn't to dispute 'Long Covid' more to say LC is just one more aspect of MCAS or HIT and it really can be treated. It's total pain in the arse, though.
I am hoping continous is the answer for me, as this last six months after finally feeling well has been heartbreaking, but before all that with my HIT under control I was back to work, back exercising, and back to my old self and tolerating HRT well. I'm hoping I can get back there again, but I couldn't have done it without drugs first, as my histamine was just off the charts.
Anyway, you've given me hope and reassurance that continous might be the answer I need now, and I hope you can find your way back to your old self, the dark days of histamine I wouldn't wish on my worst enemy.
In happier news, I slept like a LOG last night, I'd been starting to panic that continous prog had messed up my sleep but fingers crossed.
Happy to chat histamine if that's useful,
Reb
