Diagnosis
A doctor can diagnose any unusual tongue bumps with a physical exam and medical history. Irritation and inflammation might cause redness, swelling, and changes in color. Also, hard lumps and painful sensations can indicate several issues with your tongue. When the doctor is suspicious of a more serious condition, he or she might do a blood test to rule out an infection like tuberculosis or syphilis. In addition, a biopsy is necessary to detect any sign of cancerous cells. [5]
