Red spots on tongue usually occurs due to b12,folic acid deficiency
It is also seen after dyspepsia
and recurrent acid reflux
Start complete course of b12,folic acid. Intra muscular injections of b12,folic acid will be helpful to get fast recovery.
Apply oral gel (choline salicylate,lignocaine) to subside pain and inflammation.
Take rebeprazole/pentoprazole with domperidone
to recover the dyspepsia and acid reflux.
Avoid oily,spicy food.
Consult your physician for better guidance and proper medical management.
