Hi Jari, for women who have a womb, all oestrogen in hrt whether pills, patches gel etc causes the lining of the womb to build up so its not just the gel...that's how hrt works which is why ladies with a womb need the progesterone component whether peri or post meno.
As with anything some hrt preparations agree with some women and some don't. So I couldn't take Evorel of an kind, conti, or sequi, couldn't take Femeston, Premarin and Provera, Tridestra, Elleste duette and solo and PrempackC (now discontinued). They either didn't work or made me feel ill as you describe. I was particularly bad on Femeston, Evorel and Provera and yet there are women here who love all of those and they work fine for them. Why they work differently inside different bodies, no one knows...if they did then most of the ladies would not be on the forum.
To be honest those having problems need huge amounts of patience and resolution to keep trying different preparations until they find what works. For me it wasn't until oestrogel and vaginal utrogestan that anything worked properly and made me feel well. Some just give up and suffer when in fact there is something out there which would make them feel well, they just didn't go far enough to find it - that's their choice but for some of us that's not an option either. My life before my current regime was not worth living and that is no exaggeration just for effect and if I hadn't persisted, I know I wouldn't be writing this post. I also know that if I hadn't kept trying I would have missed out on what made me feel well.
You chose not to try loads of stuff but you have been lucky in that your symptoms from meno are ok for you to live with without hrt - as I said there are plenty of us for whom that is not an option. My life started to go really down the pan at 45 and I am now 57. Between the ages of 52 and 56, it was one long daily nightmare. I have been on the right regime for me 1 whole year and now I have a life. Ladies having a difficult time with meno and meno drugs can find the right thing for them, but the key, I think, is not giving up until you have gone through the prescription book.
Jefner, I think your thyroid issues are playing a part - search the forum for other ladies posts who are using hrt and have thyroid issues for their views and to find out what they are doing. x
