Hi sir It seems like you have mild ulceration in the hard palate and tongue region ( based on image). Consistent burning sensation needs to be addressed sir. Please visit the nearby dentist and he/she will examine your oral cavity. For symptomatic relief i will suggest 1) Mucopain gel 2 times daily 2) Tab zincovit 0-0-1 for 5 days. But you need to visit the dentist as early as possible.

Burning of the tongue and palate for 45 days, especially when it is present throughout the day and the palate feels rough/sandpaper-like, needs an in-person oral examination rather than just empirical medication. Possible causes include irritation/trauma, fungal infection, reaction to toothpaste or mouthwash, nutritional deficiencies, dry mouth, or a burning-mouth-type condition. Persistent burning symptoms are evaluated by an oral medicine specialist when the dental examination does not identify a clear cause. Because this has persisted for more than a month, I would not assume it is simply a minor ulcer. A persistent oral lesion or unexplained mucosal change should be examined.
