Suggest Remedy For Swelling And Soreness In Vagina

My husband and I used a vibrartor "sex toy" last night. At 3 in the morning I felt extreme pain. I inserted my fingers to find one of the batteries had fallen out and was in my vagina. It was only in their a couple of hours, however the disc battery was already corouted. My tissue is extrmemly swollen and very sore. Will I be ok? What should I do?
