What Is Low Back Pain?
The human spine contains 33 bones known as vertebrae stacked upon each other and separated by a gelatinous structure known as intervertebral disc which acts as a shock absorber. Low back pain can result from a strain (injury) to muscles or tendons in the back or injury to the disc making them herniated or prolapsed. Other causes include arthritis, structural problems and disk injuries. Pain often gets better with rest, physical therapy and medication. Reduce your risk of low back pain
by keeping at a healthy weight and staying active.
What causes back pain?

Most commonly Back pain results from repetitive injury or overactivity over back which leads to muscle trauma and stress called as Muscle STRAIN. Other causes for back pain are described below –
Poor posture with Bad ergonomics
Mostly back pain is caused due to everyday activities and poor posture. Such activities include working out too much, prolonged sitting or lying down, sleeping in an uncomfortable position, or wearing a poorly fitting backpack.
Herniated Disc
Herniated or ruptured discs often result in severe back painmay or may not associated with radicular pain radiating to legs.
Degenerative Changes
Degenerative changes in the spine called as spondylosis. It occurs when the functionality of the spine begins to wear or tear due to ageing process.
Medical problems Several medical conditions such as kidney and spine infections or tumors and sleep disorders also contribute to back pain.
Symptoms along with back pain which Require Urgent Care
See a health care professional any time you have back pain after a fall or injury. The same goes if you have back pain with bowel or bladder control problems, leg weakness, fever, or pain when coughing or peeing. 

Who’s at Risk for Low Back Pain?
Most people experience back pain first when they’re in their 30s. The odds of additional attacks increase with age. Other reasons your low back may hurt include:
 Being overweight
 Being sedentary
 Lifting heavy stuff on the job

Diagnosis for back pain
Physical examination: After studying the symptoms and medical history, a physical examination of the patient is performed. During the physical test, the doctor examines your back and assesses your ability to sit, stand, walk, and left your legs. It is done to understand better the muscle strength, reflexes, and neurological condition of the patient.
Imaging studies: When a specific condition is suspected of giving rise to back pain, imaging studies like Xray or MRI is advised to the patient.

Back Pain Treatment
The following treatment methods are provided and advised to the
patients with back pain:
Medications
Back pain can be cured by nonsteroidal anti-inflammatory drugs such as ibuprofen, aspirin, and naproxen. Other prescribed medications include topical rubs, ointments, opioids, muscle relaxants, and epidural steroid injections. 
Physiotherapy
It includes acupuncture, IFT, manual massage along with stretching and strengthening excercises.
Surgery Surgeries for back pain are usually recommended in case of those structural abnormalities which don’t respond to the medications and therapies. The surgeries aim to cure symptoms such as numbness and persistent pain in the legs caused by stressed nerves in the spine. These decompression surgeries work by removing a bone spur or a herniated portion of the disc that presses on the nerve root from the spinal column.
