Sore tongue ,

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the sore tongue with white and red patches all over it.
You seem to be having the canker sores (aphthous stomatitis) which can be painful. Many are round, but sores may be irregularly shaped. They usually last 7 to 10 days and heal without a scar. They often recur. Prescription drugs that resemble corticosteroids, such as triamcinolone, or anesthetics, such as lidocaine or benzocaine, can be applied to the sores to help them heal.
Another possibility to consider in your case is thrush which is a fungal infection. It tends to develop in the mouth in people who take antibiotics or have a dry mouth. Thrush often appears as a white, curd like film coating the gums, including the gums under dentures, and the inside of the mouth. Thrush is usually painless, although the affected areas sometimes appear red and burn. Thrush may also affect the corners of the mouth, which become cracked, red, and dry. Antifungal creams and rinses are effective in most cases. When thrush is severe, antifungal drugs may be taken by mouth.
You must consult your personal physician for definitive diagnosis as the same is not possible online.
Hope this helps. Take care.
