Hi..
Thanks for the query..
Red spots on the tongue along with raw feeling and bumps on the inner lip can be due to inflammation inside mouth causing Stomatitis and Glossitis and the red bumps on the tongue can be due to lingual pappilitis that is inflammation of the tongue papillae..
It can be due to a number of causes like
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 etc..
You need to consult an Oral Physician or a general
dentist in this regard to get evaluated and treated..
For now you can do warm saline gargles.
Gargles with 1:1 solution of benadryl and
milk of magnesia can help..
You can also gargle with specialised mouthwash like Magic Mouthwash if available in the pharmacy in your area.
Apply numbing gel over the sore for relief from pain especially during eating..
Take a vitamin b complex tablet for a period of 15 days..
Avoid spicy, sour and acidic foods..
Hope this information helps..
Regards..
