<s>[INST] my 3 year old son has been sick with a fever the past 3 days. Well today I went to give him a bath and noticed that his ball sack is hanging but its empty. I can feel both of his balls but they are a lot higher than the hanging skin they used to fill. Should I be worried? [/INST] Hi... by what you say this looks like a bilateral a retractile testis. As long as you are able to feel the testis outside the abdomen and they are visible to you, you need not worry.But if you are still in doubt you can consult a paediatric surgeon and get clarified after clinical examination.Regards - Dr. Sumanth </s>
