Hello, I have read your your inquiry and understand your concern. I can only suggest treatment of symptoms for your mouth ulcers since you are experiencing a wide range of systemic affects. I suspect you have activated a viral type of reaction in your mouth. You are correct to have balanced vitamins and proper nutrition. Avoid irritants such as smoking and alcohol. Make sure you have adequate vitamin B complex. Warm salt water rinse cleanses and soothes your gums. Maintain good day dental care and include brushing your tongue. See your dentist to rule out dental problems such as broken teeth, infections and periodontal conditions that need treatment. A dry mouth can promote oral infections including bacterial, fungal and viral in nature. Your dentist can examine your mouth and diagnosis any of theses conditions. Keep well hydrated. Rest and lessening stress can reduce chances of ulcers returning. Take anti-inflammatory medicine such as Tylenol or Advil. Benadryl, an antihistamine may help discomfort reducing inflammation. Ask about a rinse combination of pain relief, anti-inflammatory and treatment medicine such as Nystatin for a fungal condition if you are having much discomfort. Thank you got your inquiry. I hope my recommendations are helpful and you feel better soon.
