Lower back pain is a common complaint. When back pain occurs on the lower right side, causes can include sprains and strains, kidney stones, infections, and conditions that affect the intestines or reproductive organs.
A sprain occurs when a person overstretches or tears a ligament, whereas a strain refers to a torn tendon or muscle. According to the National Institute of Neurological Disorders and Stroke, strains and sprains are the leading causes of acute back pain.
Causes of sprains and strains can include: lifting heavy objects or using improper lifting technique, twisting or jerking the body awkwardly, overstretching or not warming up properly before exercise and falling.
Muscle-related back pain can range from mild to severe. The symptoms of sprains and strains can include: aching, stiffness, or tenderness in the lower back restricted range of motion due to lower back pain difficulty standing or sitting upright, lower back pain that radiates into the buttocks muscle spasms in the lower back
The type of treatment will depend on the cause and severity of the symptoms. A person can treat mild sprains and strains at home with rest, ice packs, and over-the-counter (OTC) pain relievers, such as acetaminophen and ibuprofen.
For people with more severe sprains and strains, a doctor may prescribe muscle relaxants and stronger pain relievers to help manage symptoms. Other treatment options can include: physical therapy, gentle massage, stretching exercises, electrical muscle stimulation and surgery.
Spinal stenosis is a narrowing or compression of the spinal canal, which is the area inside the spine that contains the spinal cord. This narrowing places pressure on the spinal cord, which can cause numbness and pain that radiates to the lower back, buttocks, and legs.
Treatment options for spinal stenosis include anti-inflammatory medications, physical therapy, and steroid injections. Doctors may recommend surgery for people with severe spinal stenosis.
Appendicitis
The appendix is a small organ that connects to the first section of the large intestine. The exact function of the appendix remains unclear, but it may help support the immune and digestive systems. Appendicitis is an inflammation of the appendix that may occur due to a blockage or an infection.
It typically causes intense pain in the right side of the abdomen. This pain can also radiate to the right side of the back. Other symptoms of appendicitis include: bloating or excess gas
swelling of the abdomen
loss of appetite
nausea
vomiting
constipation or diarrhea
Appendicitis requires immediate medical care. People who think that they may have appendicitis should go to an emergency room immediately. Treatment typically involves surgical removal of the appendix, which is a procedure called an appendectomy.
Kidney infection
Bacterial or viral infections that affect the urinary tract can move upstream into one or both kidneys. If a person does not receive treatment, a kidney infection can lead to serious complications, such as chronic kidney disease, kidney failure, or sepsis.
Symptoms of kidney infections include:
pain on one or both sides of the back
nausea and vomiting
cloudy, dark, or bloody urine
foul-smelling urine
frequent urination
a burning or painful sensation while urinating
chills and fever
People with symptoms of a kidney infection should see a doctor as soon as possible. Treatment for kidney infections usually involves a course of antibiotics. A doctor may also prescribe pain relievers to help ease a person’s symptoms. Drinking plenty of water is important to prevent dehydration and fever.
