Whitehead like pimple on corner of mouth/on lip area where a coldsore would normally be. not coldsore as it didn't itch or hurt, until i popped it, but everytime i squeeze out pus it refills after 30 mins into a puss filled pimple again. not healing?

Do not squeeze or pop whitehead or a pimple,especially on your lip. It could lead to disfigurement or scarring. Apply hit (not too hot) compresses. Apply rubbing alcohol to surrounding areas to kill any staph bacteria if pus comes out. Apply antibacterial cream. If there is progressive swelling,increasing pain,tenderness or redness, go to a physician or to the ER for treatment.
