[|Human|] Hello, about a week ago I hit the back part of my leg close to the knee on the left side against the corner of my coffeetable. It s still a purpleish shade bruise and theirs a hard lump just off of the center of the bruise. It feels about 1cm in diameter and 0.5cm high. I have not been aware of this lump until this morning.
[|AI|]  Hi. Can understand your concern.AS per your complaint as you have got hit against the sharp edge of the coffee table there must be rupture to minor blood vessels as well as trauma to the delicate soft tissues leading to inflammation and redness, pain, swelling are signs of inflammation. The bruising occurs due to hematoma formation when the blood leaked from ruptured blood vessels spills into the soft tissues and forms a hematoma. The inflammation leads to accumulation of inflammatory cells, formation of fibrous tissue and at times encapsulates the hematoma forming a hard lump. You need not worry as slowly the lump will resolve. Do alternate warm and cold packs over the lump. Apply thrombophob gel over the bruised area and the lump. In case of pain you can take anti-inflammatory painkiller like Ibuprofen or Advil. Hope this information helps.
