I was fingered by my boyfriend last night and it was quite rough. Afterwards I felt sore beteeen my legs and felt down below and my left labia minora had swollen up to about three times its size. This has happened before but last time it was back to normal within 12 hours and it's currently the same size as it was last night. I've been icing it and taking anti inflammatory tablets. Is there anything else I can do and can it be prevented in the future?
