Hi.. Thanks for the query.. It looks more like that you have git an allergic reaction leading to peeling of the mucosa inside mouth and along with it there is raw feeling due to severe inflammation.. It does not look to me like Oral Thrush, however a clinical examination is a must to rule out the exact cause. If there is a white coating over tongue then it can be probably thrush and a microscopy of the scrapings from tongue can help in confirmation.. If the symptoms are very severe you can consult an Oral Physician or ab Emergency room and get evaluated. A steroid shot and a steroid mouth rinse can help in reducing inflammation and pain.. You can also suck ice pops or do cold water rinses.. You can gargle with specialised mouthwash like Magic Mouthwash.. Avoid spicy, acidic and citrus foods.. Take Vitamin B complex supplements.. Hope this helps.. Regards.
