Hi there,
I seem to have noticed a tenderness on the underside of my scrotum, at the medial ridge (where the left and right scrotal skin meet) with some heat and inflammation. I disregarded it first, thinking it was from the new pants I was wearing.
However, I noticed an increase in severity of the pain (from 2 to 4) and the inflammation seemed to worsen. I had a hard time observing it as it is on the underside of my scrotum. Upon palpation, the ridge seemed to inflame and the inflammation was ascending, about 2-3 inches below the base of my shaft. Along the inflamed ridge, there are 3-4 "bumps" starting from my perinium to the tip of the inflammation. The last bump seems to resemble that of a pimple, with a white center.
I am a monogamous sexual partner for almost 4 years now, and only now has this problem presented.
