Conversation: The conversation between human and AI assistant.
[|Human|] I had a dental novicaine injection for a temporary crown in a molar.  The Dentist said that I have a blood blister in my jaw from the injection.  He told me to take an antiinflammatory and it should go away.  It is very painful.  What else can I do to relieve the pain?
[|AI|]  Hello, Your body needs to absorb the blood that has pooled. If after 48 hours use heat to increase circulation and improve healing. Anti-inflammatory medication such as Tylenol or Advil is advised. Avoid massaging or added stress to the area. You don't want any additional bleeding which would cause more pressure. Keep well HY Chat Doctor.  The swelling should slowly resolve. Follow proper nutrition with balanced vitamins and maintain gentle, good daily dental care. Contact your dentist if area does not continue to improve. Don't be alarmed if a hard area develops as a process of healing. This will usually continue to resolve with time. Thank you for your inquiry. I hope you will feel better soon. I am available to answer additional questions.
