[|Human|] After a fall that hurt her right thigh my mother bruised at the site of the injury and under the knee. the bruise remained for a couple weeks then subsided but now she feels like a hard knot is all the way inside where the injury was. What could that be and how could it be treated
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concern. As per your complaint it seems that due to injury caused by fall there has been inflammation of the soft tissues and also ruptured blood vessels leading to swelling, bruising and hematoma formation. As the inflammation subsides the swelling resolves while the disintegration of blood from soft tissues can resolve bruising. While at times the Hematoma gets encapsulated and localized and becomes a firm lump that can take a longer time of about months to resolve. In your case if only seems to be the case. You can do alternate warm and cool compresses over the lump 2 to 3 times a day. Apply Thrombophob gel that will help in faster disintegration of the clot. In case if the lump does not regress in a month consult a General Physician and get evaluated. Hope this information helps. Thanks and regards. Chat Doctor.
