Quote from PrimalSympathy:My Boyfriend suffers from constant canker sores, to the point where he says it hurts to move his lips or brush his teeth. He's had this for a long time. He does have low testosterone, could that possibly cause this? Anything that could help?
Are they canker sores or cold sores. Here is some information between the two and treatment. I hope this helps you.
Canker sores differ from cold sores in that they occur in the soft tissues of your mouth and aren't contagious. Conversely, cold sores rarely develop in the soft tissues of your mouth and are extremely contagious because they're caused by a virus.
Your doctor may suggest prescription medication if your sores are large, painful or persistent. To relieve the pain and irritation of canker sores, your doctor may recommend a prescription mouthwash, a corticosteroid salve or an anesthetic solution called lidocaine (Xylocaine, Mylocaine).
Cold sores are quite different from canker sores, a condition people sometimes associate them with. Cold sores are caused by a form of the herpes simplex virus, and they're contagious. Canker sores, which aren't contagious, are ulcers that occur in the soft tissues inside the mouth, places where cold sores don't occur
If you experience frequent bouts, your doctor may prescribe an antiviral medication to treat cold sores. Commonly used antivirals include acyclovir (Zovirax), available in both pill and ointment forms, the oral drugs famciclovir (Famvir) and valacyclovir (Valtrex), and the ointment penciclovir (Denavir).
Using a medication may shorten the duration of cold sores, but it won't prevent recurrences.
