hello. the most common cause for your pain is a tooth with abscess. there are high chances of a deep cavity/caries which has reached the nerves inside and caused pus/abscess formation. considering other things normal, a root canal treatment may be required to cure you of this pain... no medicine can cure it permanently. please visit a good dentist near you and get the treatment done as soon as possible. best wishes
