A varicocele often produces no signs or symptoms. Rarely, it might cause pain.
The pain may:
- Vary from sharp to dull discomfort
Increase with standing or physical exertion, especially over long periods
Worsen over the course of a day
Be relieved when you lie on your back
- With time, varicoceles might enlarge and become more noticeable. A varicocele has been described as looking like a “bag of worms.” The condition might cause a swollen testicle, almost always on the left side.
