Thank you for the question.
Without the benefit of a proper examination, it is difficult to be sure of the cause of the itch and lump. Common causes of vaginal itch include fungal infection and eczema.
There are also many causes of a lump near the vagina. These include a prurigo nodule, viral wart, cyst and benign or malignant skin growths.
It would be best for you to see your doctor for a proper assessment of your condition so that an accurate diagnosis can be made.
