Hello,
Your symptoms of red painful and swollen tongue and the inside of mouth is appearing to be due to a condition known as Apthous Stomatitis causing Glossitis that is inflammation of tongue.
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,
uncontrolled diabetes and other immunocompromised conditions et cetera.
You need to consult an Oral Physician or a general
dentist in this regard to get evaluated and treated.
For
Aphthous Ulcers, you can do warm saline gargles. Gargles with 1:1 solution of Benadryl and
milk of magnesia can help. You can gargle with a specialized mouthwash like Magic Mouthwash. Take a multivitamin tablet for a period of 15 days. Avoid spicy, sour and acidic foods.
In case if still the condition does not subside, the physician can prescribe you to take a steroid course as it is the ultimate treatment in case if nothing else works.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
