Chronic blisters on the tongue can be caused by recurrent aphthous ulcers (canker sores), oral lichen planus (an inflammatory condition), nutritional deficiencies (such as vitamin B12 or iron), or sometimes mild autoimmune responses. Because this has lasted for five years and makes eating difficult, I highly recommend seeing a dentist or an oral medicine specialist. They can safely examine your tongue to find the exact cause and offer targeted relief. Meanwhile, try avoiding spicy, acidic, or salty foods, and rinse with a gentle, alcohol-free mouthwash to help soothe the soreness.
