Brief Answer: Viral infection most probably, see doctor Detailed Answer: Hi and thanks for the query, It is clear that there is an active inflammatory reaction going on at the lebel of the mouth. It might be important to note if you have experienced any fever or have any associated lymph nodes around the head region or not. The lesion presented is more of a viral infection. The commonest of viral infections that could present as such are Oral herpes infections. Ii is true that others could also present as such, but this is the most probable in this case. Using oral antiseptics and analgesics could be sufficient. Doing a serological test for oral herpes could be necessary. Based on test findings, specific drugs could be prescribed. Treatment is generally symptomatic with pain killers and antiseptics, except in very severe cases as would indicated by the results of your doctor s physical examination or degree of infection based on results of serological tests. I strongly suggest you consult your primary care doctor for a proper review. Please, d feel free asking further questions in case of need. Kind regards as I wish you the best of health. DR Bain
