Sore in throat: Canker sores are rarely found in the back of the throat. That being said, If it is a canker sore, it will resolve itself in 7-10 days. You should consult a dentist, oral surgeon or ENT specialist to confirm exactly what type of sore you have in your throat. If it has lasted for more than 10 days, or if it has re-occured, have it checked ASAP.

I am 16 week pregnant, I have canker sore in my throat, is it safe orajel for my baby?

Yes: No problem with this. Do not overdo it because you may make it worse. Warm salt water rinses (1 tsp/8oz) 4-5 times a day really help. Dry the area with a Q-tip first then apply oragel or baby oragel with a Q-tip. Good Luck. Good to consider the effects on your baby.

Please tell me, could a canker sore spread to my throat?

Please tell me, could a canker sore spread to my throat?

Unlikely: A true canker sore is a local auto-immune condition that results from different types of stress. It usually doesn't "spread" as you describe. If you have large patches in your mouth that are ulcerating, then that is indicative of a larger systemic auto-immune problem. Otherwise, you likely have a pharyngitis that is unrelated to the canker sore. Either way, you should see a physician.

What to do if I have a painful canker sore in the back of my throat, what can be done?

If you can see it: And access it with a cotton swab, try a product called zilactin (many pharmacies carry). Place a small drop on the small swab and apply a thin coating over the canker (grab on to something- burns a little at first....) let your dentist treat it w other medications or a laser if you can. 10-14 days is the usual course for resolution. Good luck!

I think I have a soft palate canker sore in the back of my throat, it hard to put an ointment on it cause its so far back. How do it treat this?

I think I have a soft palate canker sore in the back of my throat, it hard to put an ointment on it cause its so far back. How do it treat this?

Mouth rinse: Unfortunately there are no good remedies for canker sores and causes are often unknown. The best treatments are usually just to treat pain, not to cure the sore. My personal favorite is what most call magic mouthwash. It is 1/3 Benadryl (diphenhydramine) (to reduce inflammation), 1/3 viscous Lidocaine (to reduce pain), and 1/3 maalox (to make it stick). You rinse and spit or swallow. Ask your dentist about it.

I developed a 'canker sore' on the back of my throat near my uvula. HSV swab negative. Is this normal?

Impossible to say: The "canker sore" you described, could in fact be a canker sore. If it last longer than 1 week, I would suggest you have it evaluated by a health care professional, preferably a dentist.

I think I have a soft palate canker sore in the back of my throat, its extremely painful and it hard to eat food and it burns when I drink fluids.?

Viral or bacterial: Common cause can be a break in the protective surface allowing normal mouth bacteria into the tissue. This is called aphthous ulcer. Another common cause is viral. Normal cold sore virus is herpes simplex. They hurt but should resolve in 7 to 10 days. Other types of infection are possible and should be ruled out with a detailed personal lifestyle and medical history by a physician.

Canker sore on the throat and got prescribed magic mouthwash - is this something serious?

Not likely: Cancer sores are a common affliction for many patients. We do not know why it occurs, but some causes are lack of sleep, stress, and allergies. They typically resolve themselves within a few days. The magic mouthwash is just palliative (makes you feel better), by numbing and covering the area.

I have this big canker sore on the inside of my right cheek & one in my throat. Is this normal?

I have this big canker sore on the inside of my right cheek & one in my throat. Is this normal?

No: Canker sore or more specifically aphthous ulcer can be prevented by avoiding a common foam detergent found in most toothpastes called sodium laurel sulfate. Switching to biotene or other toothpaste not containing this ingredient can be the cure in preventing this painful condition. During an episode, 2000 mg of lysine in divided doses per day can decrease the symptoms and time involved to heal.
