Was on a fairground ride, went flying and the side of my face went into my brothers knee. Jaw feels really weird on one side, not hurting when kept still, but just feels not right. I can't fully bite my back teeth down or open my mouth past a certain point, when I try it feels like there's a bubble (don't know how else to describe it) that I can't get past. My teeth also don't seem to line up properly. Does this sound like it's dislocated even though it doesn't really hurt? And if so will it sort itself out or do I need to go to A&E? Thanks.
