Hello and welcome to HCM.
Thank you for your query.
Without proper visualization, examination and testing we cannot conclude a diagnosis. These bumps could be an infection, they could just be your taste buds
(you might have not noticed them earlier) or they could even be cancerous growths that might require action by a doctor.
Please consult your doctor at the earliest for a diagnosis and treatment (if required).
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
