Hi everyone. This is my first post and I suppose as with most things we only come across these forums when are searching for advice. So here goes !! I had total hysterectomy at the age off 28 due to endometriosis. Have been on HRT ever since. Im now 57. My usual HRT Zumenon has been in short supply so was changed 6 weeks ago to Progynova. Since then I've been really suffering with nausea, muscle tension, increased anxiety and tremors. Im due to speak to my GP later today and really just wanted to ask if a change in HRT could give me these symptoms. I was assured by the nurse who gave me these they were the same ?? I really don't know if it could be the Tabs. I guess I'm asking if anyone on here has had similar experiences with a change in HRT !! !Thank you in advance.
