Have had a pessary ring fitted since 2009.I was advised to attend Gynocology clinic every 6 months for a replacement ring. atThe hospital . This entailed an inspection of the uturus in case of Infection or an Alcer and inserting anew ring. Was really painful at first but I now use a cream such as replense 2 times a week and just suffer a little discomfort. Being 78 years old I couldn't have a hysterectomy due to a heart problem in 2005. Unless I had an epidural which I discounted.I am fortunate being in the UK as I don't have to pay. I have never been advised to replace the ring myself which I think I could do if requested by my GP. But feel relieved to know that I am receiving the best treatment.
