Any : Any vaginal lesion needs medical evaluation. It is hard to say what you have based on your post. However common vaginal lesions are cysts, herpes, syphilis sores, abscess (bacterial infection) etc. The bottom line here is to have a follow up appointment with your primary care provider or gynecologist as soon as possible for evaluation, diagnostic testing as deemed necessary, and treatment. Best of luck.
