I had an infection on my penile shaft. Went to the doctor and was prescribed antibiotics and received antibiotics IV. I have an appointment on Thursday but had a question before then. There is a hard lump where the infection was. All pain is gone and there isn't any swelling or redness, but I was wondering what this hard lump is? It hasn't shown any signs of going away for the past two days. I am 28 years old, 5'11", and 250 lbs. I have asthma, but other than that I don't have much in the way of medical history. Blood pressure is good, and so is cholesterol.
