[|Human|] Hi,I have a worm like lump on my penis, aproximately 4 inches long and around 1 mm thick travelling from base of shaft to the start of the head of the penis and around and underneath the head. It is under the skin, I have minimal pain and but it is sore to touch.
[|AI|]  Welcome to Chat Doctor .1. The possible cause could be dilated venous channel which need to be assessed.2. An Doppler study of penis will help to see the status of the blood supply.3. At the same time ultrasound / Doppler study helps to assess the nature of the lesion, its source and extensions.4. Other possible cause could be localized skin infection causing above symptoms - which needs a course of antibiotics.5. Maintain local hygiene, do not scratch or press the area, clean with antiseptic liquid that will help to heal quicker. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate.
