Good evening, I just arrived home from a long day of work related activities. Changing to work my way towards sleep. I stripped down and was preparing to on my boxers for sleeping. I held up my penis and scrotum to just air my area. I noticed what appears to be a blood line inside the scrotum and leading up to the trunk of the penis! This is not normal. Should i proceed to a ER or wait to try to visit my interist in the morning?
