Top 8 Mild Side Pain Causes

  1. 1.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.

    You should visit your ER. Pyelonephritis is caused by bacteria and, therefore, needs to be treated with prescription antibiotics.

    Rarity:
    Uncommon
    Top Symptoms:
    abdominal pain (stomach ache), nausea, pelvis pain, back pain, fever
    Symptoms that never occur with kidney infection (pyelonephritis):
    mid back pain from an injury
    Urgency:
    Hospital emergency room
  2. 2.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.

    Kidney stones can be painful, so go to the nearest urgent care center or emergency room. The course of treatment depends on the size of the stone. Small stones can pass out of the body without any treatment, which can take two days to four weeks. You can help this process by drinking plenty of water to increase the flow of urine. Strong painkillers can also help with the pain. If a stone is stuck in a tube (ureter), your doctor might recommend a medication called an alpha-blocker, which can help make the tube bigger and thus help the stone to pass.Larger stones might not pass on their own, and thus surgery or shock wave therapy might be used. Shock wave therapy uses shock waves to break up stones into small pieces that can pass out of the body.

    Rarity:
    Uncommon
    Top Symptoms:
    nausea, abdominal pain that comes and goes, diarrhea, pelvis pain, vomiting
    Symptoms that always occur with kidney stone:
    hidden: abdomen or flank pain
    Urgency:
    Hospital emergency room
  3. 3.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.

    You should visit your primary care physician. IgA nephropathy is treated with blood pressure medications, omega-3 fatty acids, immunosuppressants, and cholesterol-lowering medications (statins). In rare, progressed cases, dialysis or kidney transplant may be necessary.

    Rarity:
    Rare
    Top Symptoms:
    side pain, bilateral leg swelling, pink/blood-tinged urine, dark brown urine, groin pain
    Urgency:
    Primary care doctor
  4. 4.Gonococcal Cervicitis

    Gonorrhea is a common STD and 350,000 cases occur each year in the United States. It is transmitted through unprotected sex.

    You should visit your primary care physician to get tested as soon as possible and discuss treatment options. Please make sure you have protected intercourse until you have been tested.

    Rarity:
    Rare
    Top Symptoms:
    vaginal discharge, vaginal bleeding, painful sex, yellow pus vaginal discharge, heavy menstrual flow

  5. 5.Irritable Bowel Syndrome (Ibs)

    Irritable bowel syndrome (IBS) is very common problem that affects the large intestine. It can cause stomach pain, cramps, bloating, constipation, or diarrhea. Doctors think that IBS is caused by the brain sending wrong messages to the bowels, such as during times of high stress, causing physical changes.

    While many people with IBS try to cope with the condition on their own, it could make a big difference if you talk to your doctor. They may be able to recommend a variety of treatments such as medication, diet counseling, or alternative therapies.

    Rarity:
    Common
    Top Symptoms:
    fatigue, abdominal pain (stomach ache), constipation, nausea or vomiting, stool changes
    Urgency:
    Primary care doctor
  6. 6.Macrophage Activation Syndrome

    Macrophage Activation Syndrome is a rare, but life-threatening disease caused by rheumatic diseases like Systemic Juvenile Idiopathic Arthritis and Still disease.

    Given the life-threatening nature of the disease, you should go to the ER immediately for blood tests and stabilization.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, fever, diarrhea, new headache, rash
    Urgency:
    Hospital emergency room
  7. 7.Herniated (Slipped) Disk in the Lower Back

    The backbone, or spine, is made up of 26 bones called vertebrae. In between the bones are soft disks filled with a jelly-like substance. These disks cushion the vertebrae and keep them in place. Although people talk about a slipped disk, nothing actually slips out of place. The outer shell of the disk ruptures, and the jelly-like substance bulges out. It may be pressing on a nerve, which is what causes the pain.A slipped disk is more likely to happen due to strain on the back, such as during heavy lifting, and older individuals are at higher risk.

    For treatment of a slipped disk, you should consult with your primary care physician (PCP). Your doctor will perform a thorough physical examination to localize the slipped disk and rule out dangerous complications. Most people do not require surgery for a slipped disk. Treatment involves pain relief with an over-the-counter pain medication such as ibuprofen (Advil) and/or acetaminophen (Tylenol), using heat treatments, and keeping active. It is best to avoid sitting still for long periods. Walking or swimming may help as well.

    Rarity:
    Common
    Top Symptoms:
    lower back pain, moderate back pain, back pain that shoots down the leg, back pain that gets worse when sitting, leg weakness
    Urgency:
    Primary care doctor
  8. 8.Unexplained Acute Low Back Pain

    A precise anatomical cause for low back pain is rarely identified. Often, the specific cause of the pain is unknown and is likely due to strain on the bones and muscles of the back from heavy lifting, prolonged sitting, or bad posture.

    Back pain often resolves within a few weeks. You can safely manage the pain at home with over-the-counter pain medication such as ibuprofen (Advil) and acetominophen (Tylenol).

    Rarity:
    Common
    Top Symptoms:
    lower back pain, back pain that shoots to the butt, fever, back pain
    Symptoms that always occur with unexplained acute low back pain:
    lower back pain
    Symptoms that never occur with unexplained acute low back pain:
    buttocks numbness, thigh numbness, involuntary defecation, fever
    Urgency:
    Self-treatment
