<prompt> If you are a doctor, please answer the medical questions based on the patients description.I got a lump on my penis but it went fairly quickly. Then it returned about a month later and from there a spot type thing appeared. Day after day and at the moment went a dark black colour and painful to touch. Whilst cleaning it popped after a soft touch then alot of puss came out. Is this a sign?  <response>: Hi, welcome to Chat Doctor. Your history looks like there is either some infection in the penis or Urinary tract infection. It needs to be ruled out. So I would like to suggest you to visit a local doctor for local examination to rule out the diagnosis. You may need some investigations also like culture sensitivity of pus, routine microscopy of urine etc. So no need to be late. It can be cured with medicine. Good luck. Thanks.
