Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that pain and soreness of tongue and gums along with fever can be due to infection only and infection is leading to inflammation I side mouth and causes
Gingivostomatitis..
I would suggest you to start talking a
multivitamin tablet daily..
You can gargle with a numbing mouthwash containing Lignocaine to relieve pain especially during meals..
You can do warm saline gargles..
Do cool water rinses atleast 3 to 4 times a day..
You can take anti-inflammatory painkillers like
Ibuprofen..
Avoid spicy and sore foods and take a soft and bland diet..
Drink plenty of water..
In case if there is no improvement in a week consult an Oral Physician and get evaluated and a clinical evaluation and investigations like Blood tests to check for the type of infection,
serum iron and
Vitamin B12 levels etc can help in diagnosis and treatment can be done accordingly..
Hope this information helps..
Thanks and regards.
