Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain it seems that you have a white coating on your tongue that seems to be due to Oral Yeast infection known as
Oral Thrush and the redness of tongue and throat seems to be due to Apthous
Stomatitis causing inflammation of the mucosa inside mouth along with formation of Apthous Ulcers which are appearing as yellow and white sores..
The burning sensation in mouth is due to inflammation and
dry mouth..
I would suggest you to consult an Oral Physician and get evaluated and after a thorough clinical evaluation if Thrush is confirmed he can advise you antifungal medicines like Nystatin mouthwash and
clotrimazole lozenges along with plenty of Probiotics like Yoghurt and Garlic..
For Apthous Ulcers you can take
Multivitamin supplements, do warm saline gargles, gargle with numbing mouthwash containing Lignocaine, avoid spicy food..
Chew sugar free chewing gum and drink plenty of water..
Hope this information helps..
Thanks and regards.
