Hello,
It can be a bartholin cyst or a sebaceous cyst. There are glands in the vaginal lips called Bartholin’s glands. These can become painful and swollen, and an abscess can form. This often causes blockage in the main duct from the gland, and a cyst develops. This is felt as a painless, hard swelling.In such cases, antibiotics may be helpful, or surgical treatment might be required.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
It sounds like a bacterial or yeast infection...they might have a test for it at the store or health food store...I'm not sure but if it is a bacterial infection, start taking garlic (you can purchase a bottle at Walmart). Read up on the web the benefits on garlic. If it a yeast infection without sex then you might want to get a fungal supplement but I'd check with the doctor before hand. Fungus in the body is no laughing matter. Fungus can wreak havoc so slow down on breads, use honey instead of sugar (sugar feeds fungus), do not eat microwaved foods. Grains have mycotoxins in them so stay away from all grains except brown rice/barley/Qionoa, millet
