Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems like you have
fungal infection over the tongue known as
Oral Thrush and it is the cause for yellowish patches over the tongue and it can also lead to soreness in tongue and other areas of mouth causing Apthous
Stomatitis..
Itchy ears can be be due to infection extending from ears to throat and to ears due to communications via Eustachian tube..
You need to consult an Oral Physician and get evaluated and a thorough clinical evaluation has to be done and if Thrush is the cause of the symptoms he can advise you to take antifungal medicines like Nystatin mouthwash, suck
clotrimazole lozenges and eating ample of Probiotics like Yoghurt and Garlic..
Avoid using Antimicrobial mouthwash..
For sore mouth you can take
Multivitamin supplements, gargle with numbing mouthwash and suck on ice..
You can take Tylenol for pain..
Drink plenty of water and suck sugar free chewing gum..
Hope this information helps.
Thanks and regards.
