Have a canker sore or cold sore won't go away I'm scared and my vagina burns and I deal with depression and kinda in a bad place right now?

Have a canker sore or cold sore won't go away I'm scared and my vagina burns and I deal with depression and kinda in a bad place right now?

Multiple issues: Cold sores are on the external lips & respond well to topical lemon balm oil whereas canker sores are on tongue, gums or inner mouth & respond to licorice lozenges. There are many causes of vaginitis but it's readily treated-see a doc for diagnosis/treatment. While meds can help depression, exercise, counseling & supplements can help too. Vitamin/mineral deficiencies & hypothyroidism can contribute.

My cold sore went away a week ago and It left 3 small pinkish bumps that won't go away. What should I do?

Nothing: Give it some time. None of the creams are as effective as prescription valacyclovir or Acyclovir pills taken at the very onset (prodrome) of the next attack. Get your prescription now so you will be prepared to take (usually 2 Grams) at the first tingling next attack. It is very safe.

Possible infection: Cold sores can become infected with bacteria although they are initially caused by a virus. When that happens they are worse than usual and resistent to usual therapy. You could try antibiotic ointment but I would recommend seeing your doctor for a culture of the sore and appropriate antibiotics if things continue since rarely a fungus can be involved.

Is it possible to make a cold sore go away over night?

Is it possible to make a cold sore go away over night?

Possible, but rare: Very unlikely. If you see a dentist at the very earliest signs of a cold sore developing (the itch or tingle stage) and your dentist treats it with a soft tissue laser (without actually touching it) and treats it with activated oxygen (ozone) and had you apply ozonated olive oil, it will go away much faster, but probably not overnight.

Can salt help make a cold sore go away?

Can salt help make a cold sore go away?

NO: But it will not hurt. The best way to get a cold sore to heal faster is to take prescription valacylovir 2 grams or Acyclovir 4000-8000mg at the very first tingling (prodrome) warning that a cold sore is coming. The longer the delay the less effective it is, so you need to have it handy for immediate use. Forget about any creams: they don't do much. Forget about lysine because it does nothing.
