I would be pleased to answer your question .
From your history and description it looks to be a cyst which might be either a sebaceous cyst , bartholin cysts
or a Colloid cyst
which has now become infected in your attempt at removal .
You should apply an over the counter antibiotic and steroid
cream on the area to reduce the inflammation until you see the doctor .
You can take a pain killer if it is causing pain and swelling in the area .
Thanks and take care.
