Hi.. Thanks for the query.. I have gone through your query and can understand your concerns.. As per your complain bumps over the tongue along with cuts or crevices and burning sensation seems to be due to Apthous Stomatitis leading to inflammation inside mouth and along with it there seems to be apthous ulcers or canker sores.. Bumps can also be due to swollen tongue papillae leading to Transient Lingual Pappilitis.. It can be a side effect of the medication while other causes can be deficiency of iron and vitamin B12, stress, physical trauma to the tongue, allergies, acid reflux etc.. I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis.. Treatment of underlying cause will relieve the symptoms.. As of now you can start gargling with a numbing mouthwash containing Lignocaine to relieve the symptoms. You can also take a multivitamin tablet daily.. You can take anti inflammatory painkiller like Ibuprofen.. Suck ice and do cool water rinses.. Avoid spicy food.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
