yesterday afternoon I noticed that my left testicle was tender to the touch, like I sat wrong or something. Slowly it swelled up a little bit and the whole left side of became tender. I could still walk okay. Later during the night, the tenderness subsided a bit....but my scrotum area became very itchy...I itched it on and off for awhile and then noticed that the swelling of the testicle subsided but now my penis shaft had swelled up under the head like it filled up with something. Now I am sore around the scrotum area and the underside of the shaft is still swollen but seems to be shrinking. I have had epidymitis about a year in a half ago and a a vasectomy about 12 years ago. Your thoughts?
