The first thing you need to do is make a visit to your dentist. If you don't like what he tells you, or if you want more information, find an Ear, Nose & Throat specialist. There is a liquid form of Bactrim that is available in a "swish and swallow" dosage which actually works very well. A dentist also suggested the nutrition supplement Lisine, but I would certainly check with your dental professional. Lastly, if you are wearing upper and/or lower dentures, I've heard there is a fungal infection that invades the corners of your mouth due to the folds and moisture created if dentures don't fit correctly. I hope this helps. If so, please consider "accepting" my answer. I hope someone provides you with an answer you are happy with.

Always keep an open mind, but not so open that your brains fall out.

A typical cold sore only lasts for 7-10 days. Two months is quite a while! There are a number of reasons that this could be occuring. The first and most likely reason, is that your body has a deficiency. If I were you, I'd avoid caffeinated beverages, develop a healthy eating plan (including vegetables) and try to remain stress-free. I'm not sure if you're aware that stress is a contributing factor to canker sores!

Continue washing your face regularly. Especially after you eat any greasy foods. DO NOT use anti-fungal products. They will only make the corners of your mouth crack and appear more unattractive (unfortunately, anti-fungal creams are not kind to our faces).

If your sores coincide with any other symptoms, you should consult with a physician. Think back to when your sores appeared: did you do anything differently? Kiss a new person, share eating utensils with anyone?

It's important to note that cold sores are very contagious. They are USUALLY caused by the Herpes Simlex virus type (HSV-1). Of course this doesn't mean that you have herpes. But until you have this checked, I wouldn't recommend having oral-genital sex until your sores are completed healed. After two months, I wouldn't wait any longer. Better safe than sorry.

You have fever blisters which are also called cold sores.

Fever blisters are usually caused by the herpes simplex virus type 1 (HSV-1). Diagnosis is confirmed by cultures for the virus, seroconversion, a progressive increase in serum antibodies to the appropriate serotype, and biopsy findings.

The first outbreak is usually more painful and lasts longer than subsequent recurrent outbreaks. Once you have been exposed to the herpes simplex virus, the virus remains in your body and can reactivate at any time. This reactivation produces blisters. Fever blisters are seen on the corners of the mouth. The vesicles become pustular and then crust-over. Usually people have on average of about 2 outbreaks per year although some people have more.

Topical penciclovir can be used to treat recurrent HSV around the mouth. Antiviral drugs can decrease the time it takes for fever blisters to heal, reduce symptoms - especially pain, prevent lesions from occurring if taken soon enough, reduce the number of lesions developed if taken soon enough, reduce the size of lesions developed if taken soon enough, and reduce the amount of viral shedding.

1) Denavir (penciclovir) 1% cream should be applied every 2 hours for 4 days. Starting treatment within 1 hour of an outbreak reduces the time to healing by 2 days and reduces the symptoms. Penciclovir also decreases the duration of viral shedding. The earlier penciclovir is started the better.

2) Zovirax (acyclovir) 5% cream and/or oral acyclovir 5 times a day.

3) Famvir (famciclovir) 3 times a day for 5 days

4) Valtrex (valacyclovir) used off-label for the treatment of fever blisters but current studies show that higher doses than usual may be more effective.

5) People who have more than 6 recurrences per year can benefit from taking acyclovir 400 mg twice daily by reducing their number of recurrences and decreasing viral shedding. Other possibilities are famciclovir 250 mg twice a day or valacyclovir 500 mg once a day.

6) Abreva cold sore treatment over the counter medication: http://www.abreva.com/

7) Apply ice to the lesions.

8) Take L-lysine tablets.

9) Blistex or Campho-Phenique may provide some relief of fever blisters especially if applied when the sore initially appears.

10) Get lots of restorative natural sleep (e.g. 8 hours at night and a noon nap) to help restore your immune system so you have fewer outbreaks of coldsores and the ones you already have can heal.

11) Eat a well-balanced nutritious diet and drink adequate fluids daily to maintain a healthy immune system and to flush toxins through your kidneys so they are eliminated.

12) Avoid passing the virus to your loved ones by refraining from kissing while visible lesions are on your mouth.

I recommend you be examined and treated by a physician in person since your lesions have been present for 2 months. A physician can prescribe an appropriate anti-viral medication to help eliminate the blisters.
