Lower back pain on the right side of your body is a common issue for many.

The pain on the right side of the lumbar region can be caused by all kinds of problems – and this is also a difficult part because this plethora of possible causes makes it difficult to determine the real problem at times.

In this guide, we want to go over all the common reasons you might experience back pain in this region and give you a guide on what could be the reason for your right side pain.

Lower Back Pain on the Right Side
Lower Back Pain on the Right Side can be caused by a Number of Reasons.


Back Muscle or Spinal Problems

The lower back is home to some of the most overworked muscles in the human body. As a result, it’s no surprise that lots of people accidentally tear or overstretch these muscles from time to time.

Even sitting in improper positions can lead to back pain in the lower regions, especially with today’s sedentary lifestyles.

But of course, there are other possible reasons for pain in your lower right side that all are connected to issues with your spine. We have an entire section on different causes, like a herniated disc, which can cause pain to radiate near the affected area. Herniated discs can be caused by improper physical activity or just sitting without good posture for too long.

The overall point is that your lower back pain on the right side might be caused by direct muscle or tissue damage in that region. This may mean you’ll need treatment in the form of painkillers, hot and cold therapy, stretching, or even minor surgery.


Kidney Issues

The kidneys are located on either side of your spine beneath your ribcage.

But your right kidney actually hangs slightly lower than the left kidney, which can increase its likelihood to cause lower back pain on that side if it becomes infected or otherwise disturbed.

Kidney stones or kidney infections are relatively common in adults, particularly those with poor diets or who consume a larger amount of alcohol regularly.

Kidney stones as a cause of lower back pain on the right side.

Kidney problems can cause irritation and inflammation to the surrounding tissue, which can eventually expand to your back muscles or spinal tissue.

Thus, the treatable issue is the kidney problem, and it doesn’t have anything to do with your spine in general.

Kidney stones are structures that are made up of excessive insults and other minerals that are normally passed in your urine. If they lodge in your ureter, however, they can become stuck and may build up over time, making it difficult and painful to pass later.

Kidney infections are often caused by bacteria like E. coli. This originates in your bowel and can eventually make its way to your kidneys and/or bladder.



The appendix is like a miniature tube attached to the large intestine.

It sits on the lower right-hand side of your body.

More than 5% of all people will experience appendicitis at least once during their lifetime, typically between the ages of 10 and 30 years.

Appendicitis occurs when the appendix is infected and becomes inflamed.

If this is the case, the appendix will swell as appendicitis progresses, which can cause tenderness in that side of the body. It eventually becomes extremely painful all throughout your abdomen and can extend to your lower back, although the lower back is likely to be affected earlier rather than later.

Appendicitis is a serious issue and requires immediate medical treatment.

If not treated, the appendix can burst and spread infected tissue throughout your abdominal cavity, potentially causing a life-threatening incident.


Female Causes

Women have a few specific cases in which they may experience lower back pain on the right side.


This condition occurs when uterine tissue grows improperly outside the uterus. Such tissue growth can irritate the surrounding organs like the fallopian tubes or ovaries. This can manifest as cramping and dull ache-like pain in the front and side of your lower right. Surgery or hormonal therapy may be recommended to treat endometriosis.


Many pregnant women experience lower back pain on the right side from general weight gain and from their overall changing bodies.

Round ligaments also develop over time; these are connective tissues that help to support the uterus as it expands, and pregnancy often causes the ligaments to stretch. The resulting pain is not unlike general muscle soreness.

Furthermore, urinary tract infections are incredibly common during pregnancy and can cause pain in the lower right side of your back.

These are so common because of bladder compression, which occurs as the uterus expands and the baby inside the womb presses on surrounding organs.


Male Causes

Men also have a male-specific cause that might lead to lower back pain on the right side.

Testicular Torsion

This condition occurs when the spermatic cord becomes twisted; this is the core that carries blood to the testes and which lies in the scrotum. Blood flow to the testicles can be reduced or cut off, causing severe and sharp pain in the groin and lower back regions. This is a medical emergency and requires immediate surgery or the testes may be lost.
