hello and welcome to HCM forum josh.watkins,
according to the history presented by you it seems that the papillae(taste buds
) over your tongue have undergone hypertrophic changes(overgrown) and in order to provide you with the treatment, exact cause has to be ruled out, i will not be able to do that until checked clinically.
These hypertrophic changes occur due to trauma, chronic infection,smoking
but you have not mentioned anything regarding pain or bleeding from the tongue, neither about your personal habits(smoking), i assume there is none.
i would recommend you to use an antibacterial mouth rinse(twice/day) and kindly visit your concerned doctor to get the overgrowth over your tongue checked.
i hope i answered your query,
i wish you good health.
