Small pinkish red spot on penis glands. No itching,soreness,swelling. Not a open sore or pimple, no puss or inflammation.Appears one day and stays for maybe two weeks or so. Then disappears for a month or two.It does not have a scab and is not flakey or crusty. It is not raised above the surface but is smooth.It does not change shape or size,color, or location. It is about the size of a pencil eraser. Iam 70 yrs. old, in good health, take only 20mg of Benicar for blood pressure. And 1 a day multi vitamin. Do you have any idea what this could be?
