Hi, last week I got into a bike accident and landed on top of my bike. After going over the handlebars I landed on top of the bike with my inner thigh landing on the handlebars. While not particularly painful at the time, (probably superceded by more painful injuries), I ve now got a large lump in that area - maybe the size of an apple slice. It s not painful at all, and the bruises is fading, but the lump has not diminished in size. Is there cause to get this checked out immediately, or can I wait to see if my condition improves?
