Penis pain/discomfort

I've asked about this a few times but it's been driving me crazy, I can't help but ask again. A few months ago I had a minor injury which caused mild bleeding while urinating for a few days. I didn't have any side effects afterwards. However, since a week ago I've been experiencing mild pains around the bottom of my penis. I really don't know how to describe it. It's actually more discomfort than pain. I'm not experiencing pain while urinating though. I feel the discomfort mostly when I'm sitting down. What could this be and could it be related to the injury? Can side effects happen months after an injury? If you need more details about the injury please let me know.
