Hi.. Welcome to HCM.. So sorry to hear about your problem and will try my level best to resolve it to the best of my knowledge and experience.. As per your query and previous history of having viral infection over tongue, the symptoms of having bumps over the tongue that are red and white pinpoint bumps seems to be most probably due to viral infection only and most probably Herpes virus infection causing cold sores.. For confirmation, you need to consult an Oral Physician or an Infectious Medicine Specialist and get evaluated and a thorough clinical evaluation and investigations like oral swab culture, blood tests for IgG and IgM antibodies can help in confirmation of cause.. In case of viral infection you can be advised oral antiviral medications like Acyclovir, Valacyclovir and topical antiviral ointments for resolution.. Also you should keep your personal belonging separate and avoid intimate contact as the infection is contagious... Hope this helps.. Wishing you good health.. Regards..
