Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain sore tongue and throat along with white coating on tongue is an indication of Oral Yeast infection known as
Oral Candidiasis which is commonly known as Thrush..
You need to consult an Oral Physician and get evaluated and in case of thrush he/she can advise you to take anti-fungal agents like Nystatin mouthwash and Clotrimazole Lozenges for 15 days..
Taking more of probiotics like Yoghurt and garlic will help..
In case if it does not resolve in 15 days
oral antifungal medicines like Fluconazole and Itraconazole can be advised..
For soreness gargle with a numbing mouthwash containing Lignocaine especially during meals to prevent discomfort..
Chew sugarfree chewing gum as it stimulates saliva flow..
Suck on ice pops..
The dryness and burnt feeling on skin can be due to
fungal infection or can be due to
Atopic Dermatitis but exact cause can be confirmed by consulting a
Dermatologist and get evaluated and he can advise you to take oral and topical steroids and anti-allergic medication as per the diagnosis.
Cold compresses over the face can also relieve..
Hope this information helps..
Thanks and regards.
