Based on your description, the tiny nodules on the tongue are commonly benign (normal papillae/irritation). At present there are no alarming features, so conservative care like good hydration, avoiding spicy foods, and maintaining oral hygiene is advised. However, if you notice increase in size, persistent pain, ulceration, bleeding, difficulty in swallowing/speaking, or symptoms lasting beyond 2–3 weeks, please get an ENT examination for detailed assessment.

No need to worry. Drink plenty of water.  Avoid spicy and masala food. Vitamin supplements will help
