Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand..
As per your complain it seems that painful red patches over the tongue can be due to a condition known as
Geographic tongue ..
Geographic Tongue leads to disappearance of tongue Papillae from some portions of tongue leading to bald or smooth appearance of tongue.
The exact cause is not known but it is considered to be genetic in origin..
Other causes can be stress, excessive consumption of citrus fruits and spicy foods, deficiency of vitamins,
hormonal disturbance and allergy.
As there is pain or soreness in tongue you can gargle with numbing mouthwash containing Lignocaine, take
Ibuprofen for pain and do cold water rinses..
You can appply a steroid ointment over the tongue and take zinc supplements..
Take
multivitamin supplements..
Avoid spicy food..
Take time for rest and control stress by
meditation and breathing exercises..
If still there is no improvement consult an Oral Physician and get evaluated..
Hope this information helps..
Thanks and regards.
