Hi, my tounge inside pimple and blood comes up in my mouth?

Infection?: Hard to tell from the description but it sounds like it could be an access. Rinse with warm salt water until you can have it professionally checked and try not to play with the area too much. Beat of luck to you.

Bleeding: You will have to be examined to determine the cause of the bleeding, who can then provide the appropriate treatment or referral. See your Dentist or Physician to start the diagnostic process.
