Suggest Treatment For Blister Like Spot On Vaginal Area

Hi there. I had a spot on my vaginal area after shaving a few months ago that had white stuff coming out of it anytime you squeezed it but yet it no longer looked like a spot more like a scar at that stage. Afterwards it would turn red and blue and stay like that for a few days. I went to check it after a month to see if it would ooze again but instead it turned bright red with a bit of blue, there was also a few small white spots inside it and is now very sensitive and slightly soft to touch after trying to pop it. I have never heard about anything like this before. It does not seem like a normal spot. What is it and do i need to see a doctor? Thank you for your help
