Hi..
Can understand your concern..
As per your complain blackhead like bump on upper lip can be due to a bacterial infection or a Herpes virus infection, Acne, Fordyce's spot etc..
As you popped and it got injured leading to inflammation and redness..
I would suggest you to first get relieved of inflammation by applying a steroid based ointment like Prednisone 2.5% for reducing inflammation..
It is better to
consult a dermatologist and get clinically evaluated for the exact cause of the bump and treatment can be done accordingly..
If it is a bacterial infection
oral antibiotics like
Amoxicillin 500mg twice daily and topical application of
Triple antibiotic ointment like Polysporin can help..
In case of viral infection Oral and topical antivirals like Acyclovir can help in preventing further outbursts..
Fordyces spots are normal anatomical structures (Sebaceous glands) and for cosmetic purposes
Carbon dioxide laser or electro dessication can be done..
Acne can be treated with anti acne agents like tretinoin.
Hope this information helps..
Thanks and regards..
