bubble/lump in vagina

Hello, I hope someone will be able to be of assistance to me. About two weeks ago I ordered some coconut oil for my hair. I remebered that I read that coconut oil helps with vaginal yeast infections, so I decided to rub the coconut oil on my vagina. After doing this for a few days i noticed that all my symptoms of a vaginal yeast infection was gone, so I continued to use the coconut oil on my vagina. I must mention that the coconut oil had nettle, sage and rosemary herb in it. Because the coconut oil appeared to work so well I did something which I now know was silly I rubbed the coconut oil in the opening of my vagina. A few days later, I just decided to use a mirror to look at my vagina. To my shock, I noticed what looked like a air filled bubble of some sort on the inner tissue of my vagina and it also looked like some of the tissue was protruding(swollen). I haven't gone to the gyno yet because I wanted to see if it would return to normal, but so far it hasn't, although it doesn't look as swollen as it did before but the bubble is still there. I think the reason for this was probably not the coconut oil itself but the nettle, sage and rosemary herb or extract that was in the oil. Can someone tell me somthing that will help this and if anyone have had this problem previously can you please tell me what you did to get rid of this? Thankyou

ps.. sorry for the long post.
