I am a 53 year old female that has had a hysterectomy. I have recently started walking 3 to 4 miles daily and swimming. I have developed a yeast infection and my dr has called me in some medicine. But in the intermine I am using an anti itch cream until I get off work to use the medication. While using the cream I have notice a puss pocket around the entrance to my vagina. Should I be alarmed?
