[|Human|] I noticed a lump in my rib cage that was a bit tender. It wasnt red or discolored in any way. The next morning when I woke up there was an almost black bruise where the lump was. I went to my dr. and he ran a blood test to check my blood clotting levels whicChatDoctore back fine. Should I still be concerned?
[|AI|]  Hi, Welcome to Chat Doctor. Looks like you had got a hematoma (blood clot) following an unnoticed bump. It occurs when there is an injury to a vessel following trauma, leading to collection of blood in the region. The blood has now seeped till the skin to cause the bruise. It will over time change from black to blue to yellow and eventually fade away. You need not worry about that. Hope I have been helpful. Regards
