Good to hear the treatment is over. Be kind to yourself as the physical healing takes place. You must be very sore. From my experience with dryness, UTIs and tearing vaginal skin, there are vaginal and vulval moisturisers that work. For those who choose to go with oestrogen cream or pessaries, those have great success. I can't understand why your GP was not able to help so I hope your Oncologist is more informed.
I am determined to recover my sex life, I understand it will be different than before but I think work will make it better. The physical barriers are probably easier tho than the mental ones! Wishing you fast healing and a happier 2015. Love. Julie
