Getting an Accurate Back Pain Diagnosis

1. Nausea and/or vomiting

Your appendix is located on the lower right hand side of your abdomen. If your appendix is inflamed or ruptured, it is known as appendicitis (this condition most commonly occurs in people age 10 to 30).

See Lower Right Back Pain from Internal Organs

In addition to lower right back pain, appendicitis may also induce nausea and/or vomiting. And you may also experience pain in the lower right hand side of your abdomen.

If you suspect you have appendicitis, don't delay. Instead, head to the emergency room; as your condition can quickly deteriorate.

2. Unexplained weight loss

The veins in your lower spine drain your pelvis, and so they allow for a direct route of entry for bacteria into your spine. This in turn may lead to vertebral osteomyelitis, or an infection of a vertebral body in your spine.

Symptoms of vertebral osteomyelitis can include unexplained weight loss. In addition, you may experience lower right back pain, fever, and swelling around your spine.

See Osteomyelitis Symptoms

The following people are more likely to develop:

  • Elderly patients
  • Individuals with compromised immune systems
  • Intravenous drug users

3. Low blood pressure

When your aorta (the artery that stretches from your hear to your abdomen) weakens or balloons in size, it is known as an aortic aneurysm.

If you experience an abdominal aortic aneurysm, it may be accompanied by low blood pressure. In addition, you may suffer the sudden onset of abdominal and/or low back pain along with nausea.

See Abdominal Aortic Aneurysm Symptoms

Patients with high blood pressure and high cholesterol are more likely to develop an abdominal aortic aneurysm.

The bottom line is that it is better to be safe than sorry. So if you have lower right back pain combined with any of the above symptoms, make sure to seek immediate medical attention.
