Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain a flab like skin on the under surface of tongue can be a normal anatomic structure which is a fold of mucosa and is known as Plica Fimbriata..
It can also be an overgrowth of
oral mucosa following any
injury or irritation..
Bumps on the inner cheeks can be
canker sores and are self resoluting condition and can occur many a times in an individual in an year..
A bump under the tongue can be a canker sore or a traumatic ulcer and will heal eventually..
If it is bluish in colour and is compressible it can be a
Mucous cyst known as
Mucocele..
Nothing to worry as there seems nothing serious..
You should do warm saline gargles 3 to 4 times a day and wait for 1 week..
In case if there is any improvement then continue dong but in case if you do not find any improvement consult an Oral Physician and get evaluated..
Hope this information helps..
Thanks and regards..
