Chronic tongue lesions and cracks can stem from several causes, including chronic dry mouth, often a side effect of medications like isosorbide dinitrate, oral thrush, or inflammatory conditions. Since vitamin B-complex and vitamin A have not provided relief, it is crucial to consult an oral pathologist or dentist for a definitive diagnosis, which may involve a simple swab or biopsy. In the meantime, focus on staying well-hydrated, practising gentle oral hygiene, and avoiding spicy or acidic foods. Depending on the findings, targeted treatments such as antifungal mouthwashes or topical corticosteroid gels may be prescribed to promote healing.

It is quite common for Vitamin B-complex injections to cause discomfort at the injection site. As a painless alternative, you can ask your doctor about switching to oral Vitamin B-complex tablets or capsules. While they take slightly longer to absorb than injections, they are highly effective for managing weakness. Alternatively, if injections are necessary, your doctor might suggest administering the medicine intravenously (diluted in a saline drip) or mixing it with a local anaesthetic to minimise pain. Please consult your prescribing doctor before making any changes to ensure the alternative is suitable for you.
