Hi Barnes1408.
Reflux is common on hrt, so is bloating and wind, although I don't think doctors would say that....lol
I've had, and still get wind, and acid reflux , which does settle after a while, only to return!
Boobs often hurt if there's too much oestrogen, but then some ladies boobs settle too,
I had sore boobs when on Sandrena gel, which eventually got too much for me, so I stopped it. I take Femoston Conti now, which suites me fine.
If you think you need to change your hrt because of these side effects, then do so, they do say to stay on for 3/6months to see if your body adjusts, but only you can tell that by how much they bother you....xxx
