I was riding my bike on a gravel trail. I went to stand up to go faster but the chain switched gears and my foot slipped and the bike jerked to the right and I fell. When I landed I was still on the bike but on my right side so my entire right leg and foot is bruised. When my foot slipped I fell off the seat and hit my crotch on the bar. I have the most horrible looking bruise down there it s right above my crotch. It s red in the middle and then blue and purple around it. And there s like a bunch of red dots on the bruise like I got hit with a softball. And it s painful to switch sitting positions, go up or down stairs, and to stand or sit down, but not that painful. On a scale of 1 to 10 I would say 3. Could I have severely injured myself down there? Should I go to the ER?
