Hi. I am concerned because my penis has been swollen for a couple days. Until today the swelling was throughout my whole penis.

The swelling has seemed to go down throughout most of my penis,
**but now there is an obvious, somewhat large, soft lump on the underside of my penis right beneath the head.**


I don't think it hurts, but my entire penis is sensitive. I have been masturbating a lot over the last few days, before and after my original swelling.

This has never happened before. I haven't been sexually active in months, and the last time was with my faithful (now ex) gf. I trimmed my pubic hair recently, which I don't often do, and it has caused me irritation. But I'd be surprised if that's what this is.

I was going to go to my college's clinic today, but they're closed. Should I go to the ER? Can I wait until tomorrow and see the doctor on campus? please help me... :-\
