A hydrocele is a painless collection of fluid around the testicle. Think of it as a small water balloon inside the scrotum—annoying, but usually harmless.

Painless swelling is the key sign. One side of the scrotum gradually enlarges, often feeling like a smooth, squishy water balloon.

Heaviness comes next. The extra weight makes the scrotum hang lower, especially after a long day on your feet.

Size changes with gravity. The swelling is bigger in the evening and smaller after lying flat overnight.

No sharp pain. You might feel a dull ache or a dragging sensation, but nothing that stops you in your tracks.

The testicle inside feels normal. You can still feel the firm ball, it’s just floating in extra fluid.

If pain or redness appears suddenly, suspect infection or twisting—an alarm that needs urgent care.
