I'm in so much pain right now. I have one mouth ulcer at the back of my mouth and I can't open my mouth wide enough to eat a banana. I'm having to double-dose on co-codamol to ease the pain, which will probably fuck my liver but oh well. I just don't know what to do...I can't really go home because it's "just a mouth ulcer" and I'll just get told to man the fuck up. Are mouth ulcers normally this bad? I mean I very rarely get one but when I do it's absolute agony.
