Some growth below my tongue since 3 days now. I have blisters usually inside mouth (not below tongue) when I don’t follow good diet/ have irregular eating but anyway thought this was similar until I realise it happened below tongue.
It’s very painful and idk what to do about it… will it go away on its own like other blisters that people usually have ? What shall I do? Pls guide me
