A.I. Health Assistant Causes for Pain on One Side

Updated on Aug. 29, 2018

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced pain on one side. This list does not constitute medical advice.

  1. 1.Kidney Stone

    A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.

    The prognosis for a kidney stone is good, as it is not a chronic condition. Once the stone has passed, the pain will go away. However, if you have had a kidney stone, you have about a 1 in 2 chance of getting another one in five to seven years. This can be prevented by: 1. Drinking more than 2 liters (2.11 quarts) of water a day. 2. Eating a healthy diet with foods rich in calcium such as milk and other dairy products, peas and beans, leafy green vegetables, nuts, and bony fish like sardines and salmon. 3. Avoiding use of lots of salt in cooking. 4. Eating more vegetables, as they help make urine less acidic.

    Uncommon
    Top Symptoms:
    abdominal or flank pain, nausea, abdominal pain that comes and goes, diarrhea, pelvis pain
    Symptoms that always occur with kidney stone:
    abdominal or flank pain
    Urgency:

  2. 2.Kidney Infection (Pyelonephritis)

    Pyelonephritis is the medical term for a kidney infection. This can arise as a result of a bladder infection that travels upstream. A kidney infection is usually bacterial in nature, and can cause pain on the side of the stomach, high fever, nausea, and blood in the urine.

    Course of antibiotics for 7-14 days, but symptoms should begin to improve after 48 hours.

    Urgency:

  3. 3.Urinary Tract Infection

    In women, the opening to the urethra (the tube that carries urine from the bladder to the outside of the body) is very close to the anus, and bacteria from the anus can easily escape and travel up the urethra. These bacteria can infect the bladder, and cause what is known as a urinary tract infection (UTI).

    Symptoms most often go away within 24 to 48 hours after treatment begins.

    Rarity:
    Common
    Top Symptoms:
    abdominal cramps (stomach cramps), pelvis pain, sudden urgency to urinate, signs of urinary tract inflammation, urinary changes

    signs of urinary tract inflammation
    Urgency:
    Phone call or in-person visit
  4. 4.Ovarian Cancer

    The ovaries are a female reproductive organ that produce eggs as well as hormones like estrogen. Ovarian neoplasm generally affects one of the two ovaries and causes symptoms like abdominal pain, bloating, irregular menstrual bleeding, and fatigue.

    The treatment & prognosis for ovarian neoplasm are vary and are dependent on the disease severity.

  5. 5.Iga Nephropathy

    Nephropathy is damage, disease, or other problems with the kidney. IgA nephropathy, also known as Berger's disease, is a kidney disorder in which antibodies called IgA build up in kidney tissue. This results in local inflammation that may over time hinder the kidney's ability to filter out waste, excess water, and electrolytes (salts) from the blood.

    Chronic condition requiring lifelong management.

    Rarity:
    Ultra rare
    Top Symptoms:
    side pain, moderate fever, groin pain, dark brown urine, pink/blood-tinged urine
    Urgency:
    Primary care doctor
  6. 6.Abdominal Aortic Aneurism

    The aorta is the main blood vessel to everything below the neck. Weaknesses can happen within the wall of the aorta, which balloons out due to the pressure of the blood pushing against it.

    Small aortic issues can be dormant for months to years, until a sudden increase. As they get larger, they can grow much more rapidly. Prognosis after surgical intervention is highly variable, and a trained specialist must be consulted.

    Rarity:
    Rare
    Top Symptoms:
    lower back pain, side pain, general abdominal pain, abdominal pain that shoots to the back, abdominal bump
    Urgency:
    Hospital emergency room
  7. 7.Ovarian Torsion

    The twisting, or torsion, of the ovary around its surroundings. This may result in loss of blood to both the ovary and the fallopian tube. When diagnosed, this condition is considered an emergency and requires immediate surgery.

    Patients are generally discharged home within 24 hours of surgery in uncomplicated cases. The patient follows up with the surgeon 1 week after surgery, and additional follow-up is regulated as needed.

    Rarity:
    Rare
    Top Symptoms:
