Going only by the description that you have mentioned it seems that you have had an injury to the tongue (traumatic or chemical or thermal or even infectious). Such rashes normally Heal within 7 to 10 days unless complicated by secondary factors. You can use anaesthetic ointments containing lignocaine or benzocaine for temporary symptomatic relief till that time. Maintaining good oral hygiene will prevent secondary infection to those rashes. If there is no improvement within 7 to 10 days you should visit dentist for a proper evaluation to rule out other factors which need to be treated objectively.
Regards.
