Hi how are you ? I have read your query and it must not be overlooked. Complete examination and history of general body diseases is important for making the right diagnosis. This condition may develop due to various bacterial, viral or fungal infections. These may include gonorrhoea, chlamydia, bacterial uretheral infections, skin disorders such as dermatitis, metabolic disturbances such as diabetes mellitus, genital herpes infection, kidney stones and trauma to penis itself. Consult your physician as soon as possible.
