Hello there ,
Thanks for writing your query,
Appearance of recurrent swelling on the tongue indicates inflammation .
Recurrent trauma to the tongue may lead to swelling and pain.
It may be caused due to several reasons like deficiency or certain vitamins especially vitamin B12
and vitamin C.
start with multivitamin
supplements for 7 to 10 days and vitamin C lozenges will help in resolving the problem.
avoid alcohol , carbonated drinks , tobacco chewing
and smoking as these may worsen the area affected.
Apply oral antiseptic ,analgesic
ointments like dentogel or mucogel topically over the affected area
if the symptoms do not subside with this you need to consult a dentist
exact diagnosis can be made only after clinical examination and evaluation , consult an oral surgeon and get the examination done.
i hope this helps ,
