Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain an ulcer on the inside of the inner lip and as per your explanation of the presentation of the ulcer it seems to be a
canker sore only and although you get canker sore frequently on inner side of
upper lip but there is nothing abnormal in case if you get a canker sore on the inside of lower lip..
It can occur due to a number of causes like deficiency of iron and
vitamin B12,
allergic reaction, dry mouth, physical trauma, excess intake of sour and spicy foods etc, while at times there is no probable underlying cause..
I would suggest you to do warm saline gargles, apply a numbing gel containing Lignocaine to relieve pain, gargle with soda bicarb solution, suck ice pops..
Avoid spicy, sour and hard foods..
Drink plenty of cool water..
Maintain a good
oral hygiene..
Hope this information helps..
Thanks and regards.
