The most common symptom of a scrotal cyst is the appearance of a lump on the scrotum, which can be felt or seen. These cysts may be painful or painless or cause nausea. Swelling and heaviness are also common symptoms.

The primary symptom of a scrotal cyst is the cyst itself. A cyst is a closed sac filled with gas, fluid, or semi-solid substance and can be located anywhere on the body. This particular type of cyst is located on the scrotum, which is the skin and tissue surrounding the testicles. If it grows large enough, the cyst may be seen with the naked eye as a lump protruding from the skin.

Another common symptom of a scrotal cyst is a palpable lump on the testicles. This means that it can be felt with the fingers during a physical or self-examination. This is dependent on the size of the cyst, as some can only be detected with a microscope.

Painlessness is also a common symptom of a scrotal cyst. Unless the cyst is pressing against nerve tissue, it may not cause any pain or tenderness. A dull ache or radiating pain is sometimes experienced in the lower back, abdomen, or groin. The growth can agitate and cause inflammation of the testicle, scrotum, or epididymis, which is a narrow, coiled tube connecting each testicle to the vas deferens. The vas deferens is what carries sperm from the testicles to the penis for ejaculation.

Occasionally the pain from a scrotal cyst can result in nausea. This is similar to the nausea experienced from blunt trauma to the testicles. The spermatic plexus is the primary nerve connecting each testicle to the spine, traveling through the abdomen. Pain experienced in the testicles will often travel up to the abdomen, causing nausea and sometimes vomiting.

Swelling of the scrotum is another symptom. One of the most common types of scrotal cysts are called spermatoceles. These cysts are formed by excessive fluid buildup in the epididymis. The excess fluid, which often contains dead sperm, can cause swelling.

Heaviness or a pulling sensation in the scrotum is a common symptom of a scrotal cyst. This sensation is caused by the added weight of the cyst. These symptoms are more likely to be experienced if there is also swelling in the testicles or scrotum. The added weight of the fluid and skin surrounding the cyst, which is called the capsule, is sometimes noticeable.
