Hi there ms. Lacey.
I hear you. This lump you mention is most probably an infection of one of the clitoral or nearby glands (of which there are aplenty in the vaginal vestibular region)! I understand the pain you must feel. It is unclear to me from which part of the world you hail & hence unable to tell you if you will need a doctor's prescritpion for the following. Please take metronidazole
400mg three times/day & Ibuprofen
600mg three times a day for a 3 day period coupled with a single dose of fluconazole
200mg (one dose one time). This should help you out & relieve you of said symptoms. If in 36 hrs , you dont observe any relief, please go visit a gynecologist or dermatologist
to examine the lesion & perhaps will require it to be lanced & drained! Cheers & Good Luck! Wish you a quick recovery!
