hello and welcome,
do you had any spicy or allergic food?
when the tongue has started thickening?it can be due to some tongue-infections caused by vitamin -b deficiency.
this can be a case of median rhomboid glossitis.in this,due to lack of papillae erythematous mucosa becomes soft.
if it is a case of benign migratory glossitis
,serpiginous white lines surrounding areas of smooth,depapillated mucosa occurs.
final diagnosis can be made only after seeing biopsy
reports of the lesion.
in case of ankyloglossia
or tongue-tie,frenum attaches to bottom of tongue to restrict its free movement.it restricts speech.frenulectomy should be done in this case.
according to diagnosis,symptomatic treatment can be done.
take viamin becosules
visit your dentist
and get the treatment.
