Hi Booroo,
I had very bad reflux when the menopause hit me,I had never had it before, so bad that ended up with an endoscopy which diagnosed reflux, I also had burning mouth syndrome it's horrendous I had all types of mouth washes and lozenges nothing apart from HRT helped it. I didn't want to take it initially but along with all the usual symptoms I couldn't stand the burning mouth any longer and it subsided very quickly and that was a massive relief.
I also had the weird under skin creepy crawly feeling it felt like a spider had got underneath the skin right at the top of my back and shoulders and was crawling around mixed with an almost sun burnt feeling that has gone since HRT but has returned recently I think due to a change from patches to gel due to the shortages.
I hope you get sorted but thought I'd reply so you know you're not alone especially with the burning mouth xx
