Thank you so much for your replies.
You have given me a few things to think about. I felt a bit more comfortable today after using YESVM internally and externally last night, so I am going to just use Vagifem tonight without Ovestin and then use the YES again in the morning as you suggest to dilute the fillers.
I remember that when I first started using Ovestin a couple of years ago it was very uncomfortable at first for a few weeks. Maybe the swap has just caused irritation to my very sensitive skin. So, on the back of a better day I'm going to persevere and try your suggestions.
If I they don't work for me I will ask for a referral to a GUM/Menopause clinic and go back to Ovestin in the mean time. I'm hoping that having made things worse by swapping meds it will settle back down quickly and that I won't have irritated everything so much that it will take a year again....
It's amazing how this affects your mood too. Yesterday I was miserable and desperate because of the soreness, today after a bit of relief, I feel more optimistic.
