Hi.. Thanks for the query.. Your symptoms seems consistent with an inflammatory condition of the mouth known as Burning Mouth Syndrome.. It can be due to a number of commonly occurring conditions like Dry mouth, allergic reaction to any medicine or food, oral infections like Thrush, acid reflux, nutritional deficiency of iron and vitamin B12, hormonal imbalances like Hypothyroidism and diabetes etc. You should consult an Oral Physician and get evaluated and treatment of underlying cause can resolve the symptoms.. As of now you can gargle with a numbing mouthwash, take multivitamin supplements, anti-inflammatory painkiller like Ibuprofen and suck on ice pops for reducing inflammation.. Avoid hot and spicy food and chew sugarfree chewing gums as it will stimulate saliva flow.. Hope this helps.. Regards..
