Thanks for your response! I went to my regular doctor the day after my original post. He examined it and couldn't tell me what exactly was going on, but he said it looked like either a bacterial or viral infection coupled with an allergic reaction. He gave me an antibiotic (cephalexin), a corticosteroid pill, and a topical cream. He also told me to ice my lips 3x a day for the swelling. All of this seems to have worked, the next day my lips were almost completely back to normal.
Hello,
From the symptoms it can be clogged pores or irritated hair follicles or Fordyce spots. Keep the area clean and apply some topical antiseptics. use an antibacterial soap or mild soap like dove.Avoid any kind of cosmetics. Topical antibiotics such as mupirocin or neomycin containing ointment are also useful. In case the symptoms persist then please get an examination done from a dermatologist.
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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
