<s>[INST] Ive noticed a white bulging lump about 2-3mm in diameter(its like a bit circular lump) on the tip of my penis head, meatus. Its on the right side but is in the middle of the whole right side of the penis head split. It doesn t hurt or anything its just there... Is it serious? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Possibility of fungal infection is more as it is white and painless lump. The most common cause for fungal infection is diabetes and poor hygiene. So consult dermatologist and get done sugar level checked. Also get done clinical examination of lump. Avoid moisture and keep proper hygiene of private parts. Wear cotton undergarments. Avoid perspiration. Hope I have solved your query. Wish you good health. Thanks. </s>
