<s>[INST] 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? [/INST] Hi,welcome to HCM. 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. </s>
