Hi, I had gone through your query and understand your concerns.I want you tell you that Glossitis can mean soreness of the tongue, or more usually inflammation with depapillation of the dorsal surface of the tongue (loss of the lingual papillae), leaving a smooth and erythematous (reddened) surface, (sometimes specifically termed atrophic glossitis). In a wider sense, glossitis can mean inflammation of the tongue generally. Glossitis is often caused by nutritional deficiencies and may be painless or cause discomfort. Glossitis usually responds well to treatment if the cause is identified and corrected. Tongue soreness caused by glossitis is differentiated from burning mouth syndrome, where there is no identifiable change in the appearance of the tongue, and there are no identifiable causes.There may be many causes of glossitis like Anemias,Vitamin B deficiencies,Infections(Bacterial, viral or fungal infections can cause glossitis),Alcoholism,Tongue piercing,Mechanical irritation or injury from burns, rough edges of teeth or dental appliances, or other trauma,Poor hydration and low saliva in the mouth may allow bacteria to grow more readily. I will suggest you to take plenty of water and healthy and nutritious diet and go for complete blood test once. You can discuss this with your treating Doctor. Wish you good health.
