Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of burnt feeling of the tongue tip along with feeling raw on the inner side of lips and tongue with dry throat and sticking of lips are all appearing to be caused due to
dry mouth or
Xerostomia leading to Apthous
stomatitis that is inflammation of mucosa inside mouth..
Dry mouth can occur due to a number of causes like
salivary gland disorders, oral infections like thrush, side effects of medicines, mouthbreathing etc..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations as per suspected cause can help in diagnosis and treatment can be done accordingly..
As of now chew sugarfree chewing gums, gargle with specialized mouthwash like
Biotene formulated for dry mouth patients, instil artificial saliva drops, gargle with numbing mouthwash containing Lignocaine..
Drink plenty of water..
Hope this information helps..
Thanks and regards.
