[|Human|] My three year old fell off his bike while going very fast and must have crushed his groin. His testicles are very purple and red and the seedling is going down. He says they don t hurt. Anything I should watch for? Should I take him in? It was a few days ago.
[|AI|]  Thanks for posting your query at Chat Doctor. I am sorry that your son got injured. Let me mention that the scrotal area contains loose tissue where blood can come from the injury site (elsewhere) and accumulate. The blood gets degenerated eventually before getting absorbed and the color gets converted into bluish, purplish, blackish etc. Do not worry about it if it is painless. It will resolve in around 7 days on its own. But approach a doctor if he says that it is painful. Hope that I have been able to answer your query. Feel free to revert in case of further queries if any.
