Hi there. Stop freaking out. From your description, it does appear like a cyst in the region has got secondarily infected & the dot is probably the pointing head of the underlying cyst/
abscess formation. Take an antibiotic (
metronidazole 500mg) & antiinflammatory (
brufen 400/600mg depending on body weight) both 3 times daily after meals for 3 days with plenty of oral fluids eg water. Do a mild hot water fermentation & see if you can 'pop' the head & the pus may be released under cover of above mentioned antibiotics & all will be well. To answer your query, yes both warts &
herpes can present as a single lump but rare & highly unlikely in your case from your description of things. However, if my suggestions dont work, please fix an appointment with your local
dermatologist. If it does work, please take the time off to send in a positive feedback & write on my wall. Cheers & wish you a healthy active sex life & please do practice safe sex!
