I am 17 years old amd i have a very painful pump on the entrance of my vagina and it hurts to the point where i want to cry i have to keep putting a cold or warm towl to suppress the pain now this has happen before but the cyst popped but this time it hurts so bad i dont want to get out the bed.

Its super wierd because it didnt start to hurt until me and my bf had sex the other day but we had asx earlier that day and it wasnt hurting until later that day .

Can somebody please help me out ASAP
