That is a frightening and painful experience, I hope you are feeling better?
I had a problem using
vagifem, but not the pains you have gone through, but it did cause a severe reaction to my vulva, the discharge from the pessary irritated me down, I stopped using it straight away, I've read here some women are allergic to the fillers in vagifem (its not the estrogen itself).
You have had an awful reaction by the sounds of it no wonder you've lost faith in your body, other than your GP telling you to come off the vagifem, did they give you an
alternative estrogen replacement treatment for you?
