10 Potential Spontaneous Back Pain Causes

Disclaimer: The article does not replace an evaluation by a physician. Information on this page is provided as an information resource only, and is not to be used or relied on for any diagnostic or treatment purposes.

  1. 1.Premenstrual Syndrome

    Premenstrual syndrome (PMS) is a very common condition. PMS has a variety of symptoms including cramping, mood swings, food cravings, fatigue, irritability, breast tenderness & depression.

    Symptoms of premenstrual syndrome can last all the way into menopause.

    Rarity:
    Common
    Top Symptoms:
    stomach bloating, anxiety, constipation, depressed mood, breast pain
    Symptoms that never occur with premenstrual syndrome:
    constant sadness, severe sadness, post-menopausal
    Urgency:
    Self-treatment
  2. 2.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
    Symptoms that always occur with urinary tract infection:
    signs of urinary tract inflammation
    Urgency:
    Phone call or in-person visit
  3. 3.Spinal Stenosis

    The spine, or backbone, protects the spinal cord and allows people to stand and bend. Spinal stenosis causes narrowing in the spine. The narrowing puts pressure on nerves and the spinal cord and can cause pain.

    Indefinite

    Rarity:
    Common
    Top Symptoms:
    lower back pain, back pain that shoots down the leg, back pain that shoots to the butt, difficulty walking, thigh pain
    Urgency:
    Primary care doctor
  4. 4.Scoliosis

    Scoliosis causes a sideways curve of your backbone, or spine. Scoliosis is most common in late childhood and the early teens, when children grow fast.

    Chronic, but curable

    Rarity:
    Common
    Top Symptoms:
    spontaneous back pain, shortness of breath on exertion, asymmetrical shoulders, asymmetrical breasts, back deformity
    Urgency:
    Wait and watch
  5. 5.Lower Back Arthritis

    Osteoarthritis, most often simply called arthritis, is a disease of cartilage. In joints, where bones touch and move against one another, cartilage helps provide lubrication for smooth movement, and acts as a shock absorber. Cartilage is also present in between vertebrae, which are the bones comprising the spine. Osteoarthritis of the spine, also known as degenerative joint disease, happens when the cartilage between vertebrae dries out and shrinks. The vertebrae are thus not as able to move smoothly against one another. The ability to walk and perform normal daily activities can be impaired due to inflammation and pain in the lower back.

    Currently, there is no widely accepted cure for osteoarthritis, and medical care is centered on management of symptoms. General pain killers are likely to reduce pain symptoms in the short term (hours up to a day). Corticosteroid injections can reduce pain symptoms for months.

    Rarity:
    Common
    Top Symptoms:
    lower back pain, spontaneous back pain, back pain that gets worse when straightening it, back pain from overuse
    Urgency:
    Primary care doctor

  6. 6.Hamstring Strain

    A strain, commonly called a "pulled muscle," is when a muscle becomes overstretched and tears. A hamstring strain happens when one of the muscles on the back of the upper leg (thigh) is pulled.

    Most low grade strains should recover within 1 week.

    Rarity:
    Uncommon
    Top Symptoms:
    spontaneous back pain, pain in the back of the knee, hamstring tightness, sports injury, hamstring pain
    Symptoms that always occur with hamstring strain:
    hamstring pain
    Symptoms that never occur with hamstring strain:
    groin pain, hip pain, pain in the outside of the hip, difficulty moving the hip
    Urgency:
    Self-treatment
  7. 7.Ankylosing Spondylitis

    Ankylosing spondylitis, also called Bechterew's disease, is a type of arthritis of the spine. 'Arthritis' means inflammation of joints, and in ankylosing spondylitis this means that there is inflammation (irritation and swelling) between the disks that make up the spine. There can also be inflammation between the spine and the pelvis. Bechterew's disease occurs more often in men and in people who have family members with the same disease.

    This is a chronic condition.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, back pain, trouble sleeping, joint pain, hip pain
    Symptoms that always occur with ankylosing spondylitis:
    back pain
    Urgency:
    Primary care doctor
  8. 8.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.

    Rarity:
    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:
    Hospital emergency room
  9. 9.Pancreatic Cancer

    Pancreatic neoplasm affects the pancreas, an organ in the abdomen, and causes symptoms like abdominal pain, back pain, urine changes, fatigue, and weight loss.

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

    Rarity:
    Rare
    Top Symptoms:
    fatigue, nausea, loss of appetite, diarrhea, unintentional weight loss
    Urgency:
    Primary care doctor
  10. 10.Abdominal Aortic Aneurism (Aaa) Rupture

    The aorta is the major blood highway. Injuries to the aorta can cause life-threatening internal bleeding.

    An aortic injury must be treated immediately with emergency surgery. The prognosis depends on how quickly you are transported to an operating room.Recovery time is dependent on the type of surgery. Open-abdominal surgery involves replacement of the damaged section of the aorta by a synthetic tube (graft), which is sewn in place with an open-abdomen approach. It takes a month or more for full recovery. Endovascular surgery is a less invasive procedure, where the synthetic graft is threaded up to the damaged section through an artery in the leg. Recovery time is shorter, but follow-up appointments will be more frequent, as it will be important to monitor for any leaking of the graft.

    Rarity:
    Rare
    Top Symptoms:
    being severely ill, nausea, severe abdominal pain, side pain, spontaneous back pain
    Symptoms that always occur with abdominal aortic aneurism (aaa) rupture:
    being severely ill
    Urgency:
    Emergency medical service
