Hi. i was drinking some juice from a really big bottle then i still had it to my mouth when i was opening the fridge to put it back in but them i forgot the bottle was to big so when i opened the fridge it hit up on my lower labial frenulum. And for the past few days it has been swollen and red and when i pull to see how it looks it stings and pains a whole lot, sometimes when i eat too it also pains for a while then i will have to eat on the left side of my mouth. Please help it really hurts. even when i talk sometimes.
