Can canker sores in throat and mouth cause severe pain difficulty eating and swollen lymph nodes?

Yes: They can cause all these symptoms. Visit your doctor or dentist to see why theses are occurring. All the best.

Infection: Canker sores are usually not infectious. It sounds like you may have a viral infection causing mouth ulcers (swollen lymph nodes suggest this). See your doctor or urgent care for evaluation and treatment. Some possibilities are Hand-Foot-Mouth disease or Herpes.

Yes: Most often the sores are caused by the HSV-1 virus which can cause an immune response enlarging your nodes, they can be painful, and they may cause swelling. They will resolve in time, or you can see your Dr. for an official evaluation and some anti-viral medication can shorten the duration of the illness. Get well soon.

Mouth sores: This sounds severe and needs proper evaluation by a physician. I'm concerned that this is 'more' than just a simple canker sore. Not to scare you, but there are various inflammatory diseases than can be quite severe like this (vasculitis type illnesses). Of course it could be a nasty infection too such as herpes or a similar virus. Best to get this checked right away. An ID doctor can help.

Yes: Need to get to the source of what is triggering the canker sores to appear. Could be diet, spicy or acidic foods/drinks, allergies, meds, supplements, etc. Some people are just more prone to getting them.

Can cause pain: If your symptoms are severe, see your doctor. Remain hydrated and take otc ibuprofen for pain. Enlarged lymph nodes are caused by the body trying to heal you.

Canker sores: Canker sores, known as aphthous stomatitis, can be caused by a virus, which may be why the lymph nodes in your neck are swollen. This is the body's response to infection. They can be very painful and take up to 10 days to resolve. A solution of benadryl (diphenhydramine) and viscous lidocaine (rinsed and spit out) will decrease the pain. Topical anesthetics may help as well. See your pharmacist.

No: canker sores would be external and not down throat which is a sign of a more serious condition. cannot say in your particular case, but generally, multiple, painful, more inflamed, and/or having lymph node swelling is a more serious condition requiring medical attention.

Canker sores: Absolutely canker sores can cause pain in the mouth and due to their inflammation they can cause painful lymph node swelling. The real question is, "Are they really just canker sores or are they herpetic in origin!" Your physician can help you determine this and can give you treatment for either cause. Over the counter meds are available but are not nearly as effective as prescription meds.

Not uncommon: Along with all types of canker sores, it's not uncommon to experience that eating is difficult, fever and swollen lymph nodes. A gel such as benozocaine can be used to numb the sore and ease the pain.
