[|Human|] Hi, I hit my stomach yesterday afternoon with a metal dog crate. Its on the left side of my belly button. The bruise is all red and it looks like there could be some blood in the lump. What do u think it could be and do u think I should have it looked at? You can email me at  YYYY@YYYY
[|AI|]  Hi and welcome to Chat Doctor. Thanks for the query. This is probably just subcutaneous hematoma which is common after such injuries and there is no need to visit doctor at this point. You can apply cold compresses, rest and take nonsteroid painkillers. Heamtoma should subside in few days. Also you can apply heparin or vitamin K cream on it to facilitate hematoma resorption. If you start to feel nausea, paleness and vomiting you should visit doctor and do ultrasound. Wish you good health. Regards
