A.I. Health Assistant Causes for One - Sided Testicle Swelling

Updated on Aug. 29, 2018

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced one-sided testicle swelling. This list does not constitute medical advice.

  1. 1.Epididymitis

    Epididymitis is swelling (inflammation) of the epididymis, a tube that sits on top of the testicle and is involved in making sperm. Most cases of inflammation are due to an infection.

    Pain eases in a few days, swelling may take up to a week to go down.

    Rarity:
    Common
    Top Symptoms:
    nausea, fever, chills, pain in one testicle, vomiting
    Urgency:
    In-person visit
  2. 2.Intermittent Testicular Torsion

    Testicular torsion occurs when the testicle rotates which cuts off the testicle's blood supply. This causes severe pain and swelling. In the case of intermittent testicular torsion, the testicle de-rotates itself and symptoms resolve.

    Symptoms resolve within a few days

    Rarity:
    Rare
    Top Symptoms:
    nausea, testicle pain that comes and goes, vomiting, pain in one testicle, testicular swelling
    Symptoms that always occur with intermittent testicular torsion:
    testicle pain that comes and goes
    Urgency:
    Primary care doctor
  3. 3.Testicular Cancer

    Testicular cancer is a condition where cells inside the testicle begin to grow out of control, forming a lump (called a tumor). These cells may spread (metastasize) to other parts of the body.

    Outlook is better than most cancers, and your ability to have sex or have children will not be affected.

    Rarity:
    Rare
    Top Symptoms:
    testicular lump, spontaneous testicle pain, hard testicle lump, swelling of one ear
    Urgency:
    Primary care doctor

  4. 4.Testicular Torsion

    Testicular torsion occurs when the testicle rotates which cuts off the testicle's blood supply. This causes severe pain and swelling.

    With prompt treatment, it is unlikely there will be any permanent damage. It is important to get to the hospital within 6 hours of the start of pain to make sure the testicle can be saved.

    Rarity:
    Rare
    Top Symptoms:
    testicle pain, nausea, pain in one testicle, vomiting, testicular swelling
    Symptoms that always occur with testicular torsion:
    testicle pain
    Urgency:

  5. 5.Non - Serious Testicle Injury

    Being struck in the testicles is very common, and despite the intense pain that follows, rarely requires professional medical care.

    Your testicle pain should resolve in 5-15 minutes. If it lasts for an hour or more, consider a visit to an urgent care center.

    Rarity:
    Rare
    Top Symptoms:
    testicle pain from an injury, testicle injury
    Symptoms that always occur with non-serious testicle injury:
    testicle injury
    Urgency:
    Self-treatment
  6. 6.Orchitis

    Orchitis occurs when one or both testicles are inflamed. This is often caused by sexually transmitted infections like gonorrhea or chlamydia. More rarely, orchitis is caused by a virus.

    Most people begin to feel better in a few days although it may take up to a month for the tenderness to fully disappear.

    Rarity:
    Rare
    Top Symptoms:
    spontaneous testicle pain, fever, tender testicular swelling, muscle aches, new headache
    Urgency:
    Primary care doctor
  7. 7.Groin Hernia

    A hernia occurs when a loop of intestine bulges out through the abdominal wall. With age, the supportive tissues that keep organs within the abdomen become weaker, and the risk for a hernia increases. Groin hernias, called inguinal hernias, are the most common type. They often result due to muscle straining, such as during heavy lifting.

    Groin hernias are not a life-threatening condition. Approximately one third of patients report chronic groin pain 1 year or longer after a hernia repair, but it is likely to dissipate over time. A hernia may recur, although the causes of this are highly variable, and depend on the degree of abdominal wall weakness and the technique of repair.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in the lower right abdomen, pain in the lower left abdomen, groin pain, testicle pain, groin lump
    Urgency:
    Primary care doctor
