Hi Dear,
Welcome to Health Care Magic Team.
Understanding your concern about oral health.
As per your query you have past medical history of stroke and
diabetes, Scrapping of tongue is probably because of
tongue bite. It could be possible you take sandwich when it was extremely hot and it caused scrapping as you have increased probability of bleeding even from minor injury because of preexisting condition of diabetes.
I would suggest you to rinse it properly first with antibacterial mouth wash or small pinch of salt in water rinse as both have antibacterial properties. Now wash your hands properly and apply pressure with ice cubes for 5-10 mins on and off. Keep drinking cold water. Avoid spicy and extreme hot food. You can take honey 2-3 times a day it will fasten healing.
Ointments such as
Anbesol can be applied as it will anesthetize tongue temporarily.
Milk of magnesia can be applied on tongue using cotton swab, it will give soothing effect.
Your symptoms will subside in 3-4 days. If it keeps on persisting more than a week then visit physician nearby you.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
