If you have lower back pain, you are not alone. About 80 percent of adults experience lower back pain at some point in their lifetimes.

Most low back pain is acute, or short term, and lasts a few days to a few weeks.


Chronic back pain is defined as pain that persists for 12 weeks or longer. The pain can range in intensity from a dull, constant ache to a sudden, sharp sensation that leaves the person incapacitated. 

Back Pain

Common Causes of Back Pain

Most back pain can have causes that aren't due to underlying diseases such as muscles or ligaments strain. In some cases, back pain can signal a serious medical problem.

Arthritis: Osteoarthritis is the main reason for back pain. It usually causes low back pain, while at times triggering complications such as spinal stenosis, which is the narrowing of the boney space around the spinal cord.

Pathological curvatures of spine: One of the most common conditions that produce back pain is scoliosis, a condition in which the spine curves to the right or left side of the body.

Sciatica: It can also be caused by irritation of the spinal nerves and due to bulging or rupturing of the disk. Sciatica pain is very specific and causes a sharp pain that starts from the back and travels down the buttock to the lower limbs.

Slip Disk: This can be due to rupturing of the intervertebral disks or bulging of it. These disks are like cushions, and align with the vertebral bones to give flexibility and strength to the spine, but when it ruptures or bulges, the disk penetrates out from the aligned spine putting pressure on the spinal nerves.

Treatments for Back Pain

If back pain keeps you up all night and medications don’t help, “back surgery” does not need to be the next step. New technology has been developed to treat back pain. They are minimally-invasive and don't require weeks of recovery in bed.

Intrathecal Pumps

Intrathecal pump is a method of giving medication directly to your spinal cord. A round metal device about the size of a hockey puck is surgically placed under the skin of your abdomen. A small plastic tube is connected to the pump and delivers medication to the area around your spinal cord.

The pump slowly and consistently releases medication over a period of time. It can be programmed to release different amounts of medication at different times of the day, depending on your changing needs. When the reservoir is empty, Dr. Salazar simply refills the pump. This procedure is completely reversible if you ever decide to have the pump removed.

Intrathecal pumps work more efficiently than oral medication. In fact, your symptoms can be controlled with 1/300 the amount of medication than when taken orally. Less medication, fewer side effects.

We currently manage over 600 intrathecal drug delivery devices.

Stimwave Therapy

Stimwave therapy uses a wireless and fully programmable device to deliver stimulation to your nerves to treat pain at its source. The device is placed with a needle next to the target nerves. You control the stimulation with a Wearable Antenna that can be clipped to your clothing. The stimulation can be programmed to personalize your pain relief on your cell phone. 

Stimwave therapy can target pain anywhere on your body. With Stimwave therapy, you can experience relief from your pain, decreased medication usage, and an improved quality of life. 

Spinal Cord Stimulator

Spinal cord stimulator interrupts pain signals before they reach the brain. SCS systems have a stimulator and thin wires that are implanted into your body. The stimulator delivers tiny pulses of mild electric current through the wires to specific nerves on the spinal cord. These impulses mask pain signals traveling to the brain.


A remote control allows you to turn stimulation on and off, increase and decrease the level of stimulation, and target different pain areas in your body using settings or programs designed specifically for you. Spinal cord stimulator systems can reduce your pain by more than 50%. 

mild® Procedure by Vertos

The mild® procedure treats neurological claudication which involves a narrowing of the lower spinal canal that causes pain in the lower back, legs or buttocks. During the mild® procedure, a doctor will remove small pieces of bone and excess ligament tissue through a tiny incision in the back to restore space in the spinal canal. It is a short, outpatient procedure, performed through a very small incision (about the size of a baby aspirin) that requires no general anesthesia, no implants, and no stitches. Study data show that 79% of patients experience a significant reduction in pain and significant increase in mobility.

Indirect Decompression by Vertiflex

As we age, the shape and size of our spinal canals change. This sometimes cause compressing of the nerves traveling through the lower back into the legs and results in pain. Indirect decompression involves introducing a small implant into the patient's spine, which relieves pressure on the affected nerves and reduces pain.
