I have had these bumps on the back of my tongue and also, I noticed a flap near my airway in my throat. For about four months, I have been told that it is nothing to worry about, but it is affecting my eating habits, and I am losing weight because I cannot swallow properly. I have type 1 diabetes, underactive thyroid, and low folate, but my diabetes is under control, and I have been on medication for my thyroid and folate for two weeks. I am a smoker, too. Please help me. It started about four months ago on my tongue and has slowly worsened over time. I am currently taking Levothyroxine 50 mg once daily, Sodium feredetate (iron 27.5 mg/5 ml), and a sugar-free oral solution of 10 ml daily. I have tried medicated mouthwash. I have done tests for vitamin deficiency, thyroid, liver, HbA1c, and complete blood count.
