A large pimple on the neck can be caused by clogged pores, excess oil production,
or bacteria. It may become inflamed, red, and painful. To treat it, keep the area
clean, apply a warm compress to reduce swelling, and use over-the-counter acne
treatments like salicylic acid. Avoid squeezing it to prevent infection. If it persists or
worsens, consult a dermatologist.
