Thanks for posting your query.
With the described features, there appears to be a large lump inside the tongue as it is interfering with routine oral activities.
You should consult with general surgeon
and should go for thorough check up.
There could be possibility of fibroma
formation (a type of cyst).
Exact diagnosis can only be made only after examination.
All these pathologies may require surgery for relief of hindrance.
