I chew caccutta 420 zarda tobaccoo for 5 or 10 minutes daily before bed and wash mymouth  thoroughly before sleeping. This I have done for years.  Now my left side back of my tongue tenderness is there. I get tingling sensation on different areas of tongue. Lift side back of my toungue some three or four very ssmall pimple like bumps have come. They are there since 3 or 4 years. They are so tender I cannot use my tooth brush for cleaniing that part of my tongue. Some verticles lines also seen in the area. Is this cancerous development? If so then what shouuld I do next?
Hello, Painful bumps can be due to inflammation of tongue papillae or can be due to ulcers on the tongue. As you are tobacco chewer, you should consult an oral physician and get evaluated. If the bumps look suspicious a biopsy can be done for confirmation. For now, apply Lidocaine gel over it to reduce pain. Avoid chewing tobacco completely. Do cool compresses over the bumps. Hope I have answered your query. Let me know if I can assist you further.
