Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from a condition known as BURNING MOUTH SYNDROME leading to burning sensation in mucus membranes in mouth and the burning sensation can also occur spontaneously even when you do not eat or drink anything hot or spicy.. It can occur due to a number of conditions like Dry Mouth, Nutritional deficiency [iron, vitamin B12 and Folic acid], yeast infection known as THRUSH, Acid reflux,medicines that reduce blood pressure, hormonal changes and imbalances like pregnancy, menstruation and menopause while at times it can occur even without any underlying cause. The medication that is prescribed to you are antibiotics [moxikind and metrogyl] and antivirals [zovirax] and these medicines cannot improve the condition until the diagnosis is made.. You need to consul an oral physician and get evaluated and treatment can be planned according to the cause.. As of now you can suck on ice pops, do cold water rinses, avoid hot,spicy and acidic foods and gargle with a numbing mouthwash especially during meals for relief.. Hope this information helps.. Thanks and regards.. Dr.Honey Nandwani Arora..
