hi do you have any curve on that side and not knowing you age does not help could be the start of pyronie's disease this could be the pain. but as for the swelling well for some of us its called an erection so from that how bad is this swelling? and is the swelling painful or something that just happens?
for the past year i have been experiencing pain in the left side of my penis which is also accompanied by swelling. have been to doctor and urologist who have ruled out stds and hernia. testicles are ok as well. what could this be?
