Brief Answer: ulcerated lesion Detailed Answer: Hello there, Welcome to HCM, I have gone through all the pictures you have attached and the signs you have mentioned in your query, the lesion below your tongue seems to be red and ulcerated. It is cystic in nature and appears like a fluid filled blister or a boil. Appearance of such ulcerated areas on the oral mucosa like tongue mucosa indicates inflammation . Recurrent trauma to the tongue may lead to formation of ulcers or It may be caused due to several reasons like deficiency or certain vitamins especially vitamin B12 and vitamin C. start with multivitamin supplements and vitamin C lozenges for 7 to 10 days which will help in resolving the problem. avoid alcohol , carbonated drinks , tobacco chewing and smoking as these may worsen the area affected. Apply oral antiseptic ,analgesic ointments like dentogel or mucogel topically over the affected area. This is the primary treatment since the lesion is acute and not chronic. If the symptoms do not resolve after 2 weeks better to go for clinical examination by an oral surgeon and biopsy of the tissue if needed. But first i would advise you to go for symptomatic treatment . i hope this helps, take care. dr.farah XXXXXXX
