White canker sores on back of throat?

My
sister has these white canker sores on t he back of her throat. she has about
8-10 and we're worried with what it is. we went to the doctors and she took 2
strep throat tests and they BOTH came out negative. she is not sexually active,
she does not have a fever anymore. we're thinking tonsillitis? but we do not
know for sure. should she go back to the doctor? help please! give us all the
info you have!
One of the most painful canker sore is in the tonsil. Canker sore in tonsils are
not contagious and neither caused by bacteria or various. It usually occurs due
to allergy to either foods or medicine or dental health products that you use.
Canker sores may be also a result of bad oral hygiene and irritation from hard
food, a break or a scratch in the tonsils may cause canker sores.

Canker sores are caused from breakdown of tissue structures and the herb named
Gotu Kola is known to heal wounds and promotes growth of connective tissues and
it is taken as brewed tea.

Rinse with alum, milk of magnesia and chicona bark are other alternative rinse
to prevent canker sores. Another effective herbal remedy is using licorice root
as it is an anti- inflammatory and tissue healer.

Combined with good oral health hygiene such as brushing and flossing, relief
from discomfort brought by canker sores is not that difficult.

But for severe cases it is always better to seek professional recommendations
from your dentist.

Paramedic here. Yes, go back to the doctor. The first cultures may have been
early and the infection didn't show up. It called also be a fungal infection
called thrush. That is not unusual in children her age. Not having a fever seems
to bear away from strep or tonsilitis. There are prescription rinses that can be
prescribed for thrush. They even make them cherry flavored or bubblegum
flavored, so munchkins like using them. I hope this helps. Mine are grown and
gone, but I remember...
It could very well be tonsilitis or just tonsil stones....however, I recently
had the same condition and I went to urgent care. Believe it or not, the first
thing they tested me for was Mono. You don't have to be sexually active or even
kissing anyone to get it. It is just a virus. I think she should go back to the
doctor and get a mono test done. It only takes 5 minutes and requires just a pin
prick on your finger. Since she isn't sexually active, she doesn't really have
much to worry about. The bad news is that if it is tonsilitis or mono, there
isn't much they can do for you. They are both viruses which means that
antibiotics wont work. Good Luck!
If the strep tests came out negative, then it's a viral infection, and should
clear up soon. She should try rinsing the back of her mouth with Peroxyl
mouthwash after gargling with warm salt water. Tell her not to swallow the
mouthwash because it contains peroxide.
How long has your sister had these white lesions? You say your sister doesn't
have a fever...anymore. So, does this mean she had one at one time? At what
point? For how long? How high did it run? Are the lesions at the sides of the
throat or the very back? Do they extend to the soft palate (roof of the mouth)?
Are they painful? How do her tonsils look to you? How is her overall health?
Does she seem to get sick often? How are her eating habits? Is her nutrition
good? What did her doctor have to say? You haven't said much about the doctor
role in all this and what she's done aside from the Strep tests.

I can't give you much information without getting a whole lot more information
from you. I can tell you that if they haven't healed in two weeks and aren't
painful, this may be something more serious than canker sores, which aren't
serious at all. She can try one of these home oral rinse treatments. Mix 4 oz.
water. 1 tsp. salt and 1 tsp. baking soda. Or, mix 2 oz. peroxide with 2 oz.
water. With either one, rinse for one full minute 4 times a day for 2 weeks.
Then reassess for effectiveness.
