[|Human|] My daughter hit front of her leg really hard 2 weeks on the table doing a cartwheel inside. It left a bad bruise and a knot. The bruise is almost gone but the knot is still there and seems to be the same size as it was when she hit it. What s caused the knot not to go away? Do I need to take her to the dr?
[|AI|]  Hi, Thank you for asking question on Chat Doctor. Bruise occurs due bleeding under the skin, and it gradually disappears. The n knot will take some more time or may remain very long time though reduced in size. Hope this answer will serve your purpose. Nothing to worry about it. Please feel free to ask any more queries if requiredTake care Chat Doctor. V. Subrahmanyam MD;Disassociate professor of pediatrics
