About Aweek Ago I Had Anal Sex And It Wasnt

About aweek ago I had anal sex and it wasnt the most comfortable due to the tightness. After that I noticed I was soar feeling down by my vagina as I also noticed one side of my vagina lips was swelling up alot an very tender all the way around to the back side perhaps due to pressure from swelling. But Being where it was maken it hard to even sit comfortable. One day I noticed some bleeding thought I was starting my monthly thing 2 weeks early. But it stopped bleeding later that night. Not real sure even if it was comming from my vagina or my anus as I was also having a hard time going to the bathroom after having anal sex. That has continued throu out the week aswell.. The swelling has gone down some in the last cpl. Days but you can feel a huge knot on the out side an yesterday We tried to have sex an it was alittle difficult beings I was swollen inside aswell I guess and alittle painfull depending on angle he was. Would it be A node or a muscle ? Will it heal by it self ?
