When To Consider Heading To The ER

Now that we have a basic understanding of the potential causes, let's look at some scenarios when you might need to head to the ER.

1. Sudden and Severe Pain

There are certain red flags that, when combines with low back pain, definitely need to be checked out by a medical professional. Sudden and severe pain is one of those red flags.

If you experience a sudden and intense pain in your lower left back, especially if it's accompanied by other symptoms like nausea, vomiting, or fever, it could be indicative of a serious condition that requires immediate attention.

Fever is a red flag for low back pain

According to the ACEP (American College of Emergency Physicians), severe pain, especially when accompanied by other concerning symptoms such as difficulty breathing, neurological deficits, or signs of infection, may warrant a visit to the emergency room.

Severe pain, along with nausea or stomach pain can signal issues with organs like the kidneys or the pancreas.

If your lower left back pain follows a recent injury or trauma, seeking medical attention promptly is crucial.

2. Trauma or Injury

If your lower left back pain follows a recent injury or trauma, seeking medical attention promptly is crucial. If you get into a car accident (even a minor one), or fall or experience any kind of injury that results in back pain, it's probably a good time to see a professional. You may have a more serious problem, like a fracture, that needs to be addressed.

The Mayo Clinic suggests that lower back pain associated with trauma, unexplained weight loss, or pain that radiates down the legs may require prompt medical evaluation. However, they also acknowledge that many cases of lower back pain can be managed with conservative measures.

3. Difficulty Breathing

If you have back pain and you are struggling to breathe properly, you should definitely seek medical advice. Often, back pain and shortness of breath result from a muscle strain or carrying extra weight.

There are times when a more serious condition can be the cause. Back pain accompanied by breathing problems can signal a potentially serious issue, like a lung problem or cardiovascular issues like a heart attack.

Numbness and tingling can be a red flag for low back pain

4. Neurological Symptoms

When it comes to back problems, any numbness, tingling, or weakness in the lower limbs, especially if it accompanies lower left back pain, could be a sign of nerve compression or some other type of neurological issue that might require urgent evaluation.

Some neurological issues associated with low back pain include things like pinched nerves, slipped discs, and spinal stenosis. All of these issues can all be caused by injury or by excessive pressure being put on the nerves over time.

The National Institute of Neurological Disorders and Stroke (NINDS) emphasizes the importance of seeking medical attention if lower back pain is accompanied by other neurological symptoms, such as weakness, numbness, or tingling.

Rest and ice can help with low back pain of moderate intensity.

Less Urgent Situations

There are instances where lower left back pain may not require an immediate trip to the ER but should probably still be addressed by your healthcare provider:

  1. Gradual Onset and Mild to Moderate Pain:

If your back pain has developed gradually and is of mild to moderate intensity, you may consider managing it initially with rest, ice, and over-the-counter pain medications or gentle exercise.

Most cases of low back pain will go away on their own after a few weeks. If, however, the pain persists, a visit to your primary care physician is recommended.

Stretching can help for mild to moderate back pain.

2. No Other Alarming Symptoms

If your back pain isn't accompanied by other alarming symptoms like fever, difficulty breathing, or neurological symptoms, it may be ok to monitor your symptoms at home while practicing self-care like gentle stretches, deep breathing (for stress management and relaxation) or using heating pads.

Follow your healthcare provider's directions for serious back pain problems.

3. Chronic Conditions:

If you are someone who has a pre-existing condition like chronic back pain or a herniated disc, which may cause intermittent discomfort, you should stick to any medical advice you have already received from your healthcare provider.

If, however, there are any sudden changes in your condition or your symptoms get worse, you should immediately make an appointment to follow up with your doctor.

Red flags and back pain should always be investigated by a doctor.


In conclusion, the decision to go to the ER for lower left back pain really depends on how severe your symptoms are and what might be causing them. Sudden and severe pain, especially when accompanied by other alarming symptoms, should not be ignored.

In less urgent situations, however, where the pain is mild to moderate and there are no other concerning symptoms, conservative management at home may be appropriate.

It's crucial to listen to your body and seek professional medical advice when in doubt.
