What are pains in lower back caused by?

There are many potential causes of lower back pain. Here are a few of the most common:

* Muscle strain: This is the most common cause of lower back pain and is caused by overuse or injury to the muscles and ligaments in the lower back.

* Herniated disc: This occurs when the soft, inner material of a spinal disc leaks out and puts pressure on a nerve.

* Spinal stenosis: This is a narrowing of the spinal canal, which can put pressure on the spinal cord and nerves.

* Osteoarthritis: This is a degenerative condition that causes the cartilage in the joints to wear away, leading to pain, stiffness, and swelling.

* Sciatica: This is a condition that occurs when the sciatic nerve, which runs from the lower back down the leg, is compressed or irritated.

In some cases, lower back pain can be a symptom of a more serious medical condition, such as:

* Kidney stones: These are hard deposits of minerals and salts that form in the kidneys and can cause severe back pain.

* Infection: A bacterial or viral infection can cause inflammation in the lower back, leading to pain.

* Cancer: In some cases, lower back pain can be a symptom of cancer, such as spinal tumors.

If you are experiencing lower back pain, it is important to see a doctor to determine the cause and receive appropriate treatment.
