10 Potential Lower Right 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.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.

    Most back pain lasts less than two weeks, and about 9 in 10 people are completely pain-free in less than six weeks.

    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
  2. 2.Iliolumbar Syndrome

    Iliolumbar Syndrome is caused by a tear of the iliolumbar ligament, which connects the hip to the spine. It's caused by overuse or acute trauma to the area.

    1-2 months

    Rarity:
    Common
    Top Symptoms:
    lower back pain, back pain that shoots to the butt, severe back pain, back pain that shoots to the groin
    Symptoms that always occur with iliolumbar syndrome:
    lower back pain
    Urgency:
    Primary care doctor
  3. 3.Low Back Strain

    A strain, commonly called a "pulled muscle," is when a muscle becomes overstretched and tears. A low back strain happens when one of the muscles in the lower back is stressed due to an unusual movement (such as lifting a heavy object, or lifting while twisting).

    This is usually a self-limiting problem, and should subside on its own within weeks.

    Rarity:
    Common
    Top Symptoms:
    lower back pain, back pain that gets worse when sitting, back pain that gets worse when straightening it, lower left back pain, lower right back pain
    Symptoms that always occur with low back strain:
    lower back pain
    Symptoms that never occur with low back strain:
    involuntary defecation, first time leaking urine, back numbness, toe numbness, foot numbness
    Urgency:
    Self-treatment
  4. 4.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.

    The pain associated with a slipped disk usually goes away within six weeks. If the pain lasts longer, consult a doctor. They may send you to see a back specialist for an MRI of your spine, and surgery may be considered.

    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
  5. 5.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

  6. 6.Pelvic Inflammatory Disease

    Pelvic inflammatory disease (PID) is an infection of the female genital structures like the uterus, fallopian tube, ovary, and the surrounding abdominal wall. It is typically caused by N. Gonorrhoeae or C. Trachomatis.

    Prognosis after treatment within 3 days of symptom onset is great (88%-100%). Those that are hospitalized, older, or have had gynecological surgery have a worse time with this infection.

    Rarity:
    Common
    Top Symptoms:
    fever, abdominal pain or unusual vaginal discharge, vaginal discharge, nausea or vomiting, vaginal bleeding, pelvis pain
    Symptoms that always occur with pelvic inflammatory disease:
    fever, abdominal pain or unusual vaginal discharge
    Urgency:
    In-person visit
  7. 7.Greater Trochanteric Pain Syndrome

    Greater trochanteric pain syndrome is a common cause of hip pain caused by damage to the tendons and/or bursa (fluid-filled sac near a joint) at the outside point of the hip known as the greater trochanter.

    Weeks to years

    Rarity:
    Uncommon
    Top Symptoms:
    lower back pain, pain in the outside of the hip, moderate hip pain, groin pain, limping
    Symptoms that always occur with greater trochanteric pain syndrome:
    pain in the outside of the hip
    Urgency:
    Primary care doctor
  8. 8.Chronic Low Back Pain of No Specific Origin

    A precise anatomical cause for low back pain can only be identified in 20 percent of cases. The rest of the time, 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, prolong sitting, or bad posture. Chronic low back pain is characteristic of back pain lasting longer than 12 weeks.

    The prognosis of chronic back pain is highly variable, and heavily dependent on the individual. However, it is not a life-threatening condition and is expected to significantly improve with directed exercises and staying active.

    Rarity:
    Common
    Top Symptoms:
    lower back pain, unintentional weight loss, back pain that shoots to the butt, fever, involuntary defecation
    Symptoms that always occur with chronic low back pain of no specific origin:
    lower back pain
    Symptoms that never occur with chronic low back pain of no specific origin:
    thigh numbness, buttocks numbness, lower back pain from an injury
    Urgency:
    Primary care doctor
  9. 9.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
