I fell a few weeks ago and badly bruised my back.. It was navy blue from my shoulder blades to my coxix.. My Dr gave me anti inflammatory cream for a large hematoma at the base of my spine. This about 3 inches round and protrudes about a centimeter. The injury happened a week before easter and although the bruising had gone ..the lump is still there an hot and painful.
Dear friend, You're having a post-traumatic bruise and lump. Bruise go away but lump still persist. You're having pain at locally and also it's going hot. All the things you mentioned are going toward a diagnosis of developing abscess. Post-traumatic hematoma and abscess is not so uncommon. You need a surgical opinion and should start antibiotics. If abscess develops, then you need surgical treatment as incision and Chat Doctor. Thanking you, Get Well Soon.
