Thanks for posting your query.
According to your description it seems you are having anxiety
after reading about a disease. In most of the men, testis hang down asymmetrically and it dose not necessarily mean hydrocele
. Hydrocele usually presents with swelling and feeling of weight in testis. It is diagnosed after physical examination by a doctor. Do not worry, and relax urself. You may need to visit your doctor to be sure.
Hope t helps,
