Hi Hope...I guess mouth sores has been the symptom of the month around here. I have had a sore tongue and roof of my mouth for two weeks. I am very prone to canker sores also and when I have an outbreak I get a fever and my glands swell. Wish I had a real answer for you. I have been put on all those designer anti-viral meds and tried OTC products also and nothing works. I just read something about vitamin B complex and extra vitamin C helping so I bought some yesterday and we'll see what happens. I have been tested for the Herpes Simplex I viurs and it came back negative. Recurrant Aptheous Ulcers...that's what they finally called it. Comes from stress. Fibro and stress go hand and hand. Don't know if this is what you are experiencing, but just telling you about my problems with it.
Sherrine swears by rubbing rum on the sores. If I had any, I'd try it!
Sore-e(cute) to hear about your woes. You get sympathy by the bucket loads from me. When I would get mouth sores it was always lichen planus, so I can't help much there.
In Mexico, they have great otc remedies. I have a specific dr. I go to when I'm there. Anyway, I have gotten, on several occassions, I series of 3, B vitamin comlex shots(Mexico is a big B believer), and they REALLY work. I also have gotten them with a pain reliever in them. My dr. here is kind of iffy on the B thing(huh, sounds like lyrics to a song). These are do-it-yourself shots.
As you may have noticed I believe in B. Get some vitamins and start swallowing or chewing. That sounds like a big ouch, what with your sore throat and all. Try not to think about work. Good luck and hope you feel better soon.
