Hello I am 47 yrs old male.Two weeks ago I founda small lump on my penis on the left side.It is about the size of an eraser on a pencil,It is movable and solid a little hard .By touch it hurts a little.A few months ago I had one in my sac and it went away after a short while.If possible please can you tell me what this may be.

Without a physical exam it is impossible to tell you what this might be. Please make an appointment with your doctor for a proper exam and diagnosis.

Could it be an ingrowing hair... that happened to my boyfriend.
