Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that red tongue,burning on eating and
altered taste is due to a condition leading to inflamation inside mouth causing Apthous Stomatitis and Glossitis..
It can be caused due to a number of reasons like Stress,
Nutritional Deficiency [Iron,
Vitamin B12 and Folic acid] , hormonal changes, acid reflux, tongue trauma due to some sharp teeth or tongue biting habit, excessive intake of sour and citrus foods, dry mouth, oral infections like thrush,allergies,
uncontrolled diabetes and other immunocompromised conditions etc..
You need to consult an Oral Physician or a general
dentist in this regard to get evaluated and treated..
As of now for pain relief gargling with Lignocaine mouthwash can help..
Steroid mouthwash can also help in reducing inflammation and burning..
Take anti inflammatory painkiller like Ibuprofen and Vitamin B complex supplements daily..
Suck ice pops, take soft and bland diet and avoid spicy foods..
Drink plenty of cool water..
Hope this information helps..
Thanks and regards..
