What causes back pain?

The most common health conditions that lead to back pain include:

1. Poor posture

Poor posture when sleeping, walking, or even working, can cause intense pain in the lower back or upper back. It can also increase the risk of other spinal changes, such as scoliosis or torticollis.

What to do: you should make changes to your lifestyle, changing your posture when working, walking or even sleeping, opting for positions that better distribute body weight and relieve back pain. Additionally, exercises such as yoga or those recommended by the physiotherapist can be performed to improve posture.

2. Muscular injury

When your back pain is localized to the left or right side, it is normally a sign of a muscular injury. This can occur after physical activity, or as the result of activity from your job (as is the case with dentists or gardeners). Normally, this type of pain feels heavy and is very uncomfortable.

How to relieve it: To relieve pain associated with a muscle injury, you can place a warm compress on the affected area for 15 minutes, twice a day, for about 3 to 4 days. You can also apply a topical anti-inflammatory ointment, like diclofenac. In addition, when you are recovering, it is important to avoid heavy activity so that your symptoms can resolve quickly. 

3. Respiratory illness

Respiratory illnesses can also cause back pain, mostly when you are breathing. The process of inhaling and exhaling requires the movement of all the muscles found in the back and abdomen.

How to relieve it: You are advised to see your doctor for treatment of the respiratory illness, especially if you experience symptoms like shortness of breath, coughing, phlegm or fever. In the meantime, you can place a warm compress in the affected area to relieve symptoms.

How to relieve it: In these cases, it is important to proceed to the emergency room for assessment and diagnosis. Through testing, the presence and size of kidney stones can be confirmed and appropriate treatment can be started. Treatment can involve medication to dissolve and eliminate the stones, as well as anti-inflammatories to relieve pain. The doctor may also opt to perform a small surgical procedure to remove the stones.

5. Sciatica

Sciatica is characterized by pain in the lower back that radiates to the legs. It is caused by compression of the sciatic nerve, which is found at the bottom of the spine, near the glutes. This type of pain is sharp and tingling and can result in difficulty with sitting or walking. Learn more about how to identify siatica and why it occurs.
