my mouth has errupted in the past 2 days into this huge swollen mess, inside there are these huge ulcers on both sides, & outside there's this gross pusy cold sure.

i never normally get cold sores or ulcers despite the copious amounts of junk i eat. what causes it? how likely is it that it's from giving head to my bf - & if this is likely, does it mean he has an std? or could it just be stress? also, how do i fix it? google says to just gargle with salt water, can you use normal salt or should it be sea salt?

also, my wisdom teeth have been coming through for a few months now, do wisdom teeth normally give people cold sores?

i've never heard of ulcers being passed from another person (I used to have them realllllly badly)
i also used to eat shite but in the end it caught up with me in the form of the most painful, disgusting ulcers in the world. i drink loads of fruit smoothies now though and i don't get them. so i guess they can be a product of your diet. also, if anyone tells you mouth ulcers can be caused by stress - its a myth. ask for some adcortyl in orabase at your chemist, its absolutely brilliant stuff for bad mouth ulcers.
i don't know much about cold sores, but they're basically mouth herpes aren't they? so you could well have caught it from your bf but its unlikely, you're probably just a bit under the weather, hence the ulcers at the same time.
eat some fruit and veg young lady!

Ulcers are often stress related arnt they?

stomach ulcers yes
mouth ulcers no
different kettle of fish

coldsores are contagious, maybe he does have an std?
