[|Human|] Not sure if I have an umbilical hernia or not; saw my internist today and she ordered an ultrasound which Im having in a few days.  She thinks its either that or possibly some sort of cyst.  In the meantime, would flying on a commercial flight across the country possibly make it worse?
[|AI|]  Hi, Thanks for posting your query. I am Chat Doctor. K and I am pleased to assist you. No ultrasound scan is not necessary to diagnose umbilical hernia. A good clinical examination itself is enough to diagnose it. But sometimes when the swelling is too small, then the doctor may have doubt regarding the diagnosis and may order for an ultrasound scan to confirm the diagnosis. Regarding the second question, the answer is - NO flying across the country does not make it worse. I hope that answers your question.
