Hi..
Thanks for the query..
I have gone through your query and can understand your concerns..
It looks like you are suffering from a severe case of Apthous Ulcers or
Canker Sores and an ulcer over the
tonsil seems to be due to either a canker sore or infection in throat..
But as you do not have other classical features of mono like
fever,
cold etc it does not seems like mono..
I would suggest you to start gargling with warm saline solution.
Gargle with a numbing mouthwash containing Lignocaine..
Take a Vitamin B complex daily..
You can take anti inflammatory painkiller like
Ibuprofen..
Avoid spicy and hard foods..
Take a soft and bland diet..
You can also suck ice and do cool water rinses..
In case of no improvement consult an Oral Physician and get evaluated..
Hope this information helps..
Thanks and regards.
