While using the restroom recently, I felt a hard sensitive spot on my penis at the base of the head right on the rim. Upon further inspection, it appeared to be a canker sore. It is oval in shape and ulcerated with a white center and is about the size of a grain of rice but more round. Looks exactly like the small round canker sores I get in my mouth occasionally, which I have been told is viral as I also get body aches and a sore neck when they are present. I have never had a sore on my penis like this. The sore resembled a concave pimple but did not produce pus or anything really when I squeezed it. Oddly enough, I also noticed at the same evening, one of my more common mouth sores coming on and strangely a couple water type blisters on the top of my right foot. My wife and I have been married 20 years and I have been faithful and have no reason to believe that she has had other partners. I suspect this is a friction burn sore but am not sure. What do you think?
For such non itchy bumps an important possibility to be ruled out is of molluscum contagiosum. Molluscum contagiosum is a common, benign, self limiting viral infection of the skin. It presents as multiple, small, dome-shaped papules, often with a central depression or plug. Treatment includes physical destruction or manual extrusion of the lesions, cryotherapy, and curettage.
