Hi Dear,
Welcome to HCM.
Understanding your concern.
The lumps inside the cheek can occur due to various reasons . If the lump is very hard the lump occur probably due to
salivary gland duct blockage (sa you also mention ) , it could be
sialolith means blockage due to stone .
If the consistency of the lump is rubbery the it needs proper medical evaluation as it can be malignancy .
So i would suggest you to consult oral surgeon for this , who may order
biopsy .
Silolith is a harmless condition , but if it bothers you or get infected doctor can remove salivary gland .
As far as your lip is concern the patch and bump occur due to continue irritation because of
smoking habit . Basically it is a
canker sore which occur due to irritation .
I would suggest you to quit smoking , apply lip balm , give col compresses and apply raw honey before going to bed .
If it continue to persist for more the a week the consult oral surgeon .
Hope your concern has been resolved.
Best Wishes,
Dr. Harry Maheshwari
