Mouth is covered in painful canker sores, please help!

i woke up one morning around a week ago with sores all over my mouth. They hurt so bad i can barely eat or drink anything except yogurt and water. I dont think this is something like herpes since I’ve been with my boyfriend for 3 months now and ive never had anything like this until now and he has never had sores in or on his mouth (and he was a virgin when i met him & we’re exclusive). The only possible cause of these I can think of is I gave my boyfriend oral sex for longer than I ever do the night before, and I went to bed with my mouth a little sore.. Next morning I had these all along my gums. If they are just canker sores from performing oral sex for too long, would they have lasted for a week already? I have about 7 on my gums & under my tongue but I could only get pictures of 3.

Gargling with salt + lukewarm water might help. Applying butter will reduce the pain.

Also if you can find Black NightShade (solanum nigrum) berries, you can consume it directly. Also their leaves can be cooked for consumption. Both are effective for any oral wounds.

These sores takes a little time to heal, so be patience. If they doesn’t heal even after a week, please consult a doctor. Good luck!
