Hi..
Can understand your concern..
As per your complain a lump can be a
canker sore or an apthous ulcer which may or may not be caused due to any underlying pathology..
It can also be a viral infection caused by
Herpes Simplex Virus leading to formation of cold sores..
At times cold and flu seems associated with cold sores but it is not a necessary finding..
It can also be due to accidental biting of tongue leading to formation of a traumatic ulcer..
In case of apthous ulcer it will get healed mostly by itself and does not require treatment..
Warm saline gargles can help..
In case of cold sore antiviral oral and
topical medication like
Acyclovir can help in preventing outbursts..
In case of traumatic ulcer also healing takes place itself gradually..
In case if the lump does not heal and is persistent for long
consult a dentist and get clinically evaluated..
Hope this information helps..
