A spinal cord stimulator (SCS) is a medical device to relieve chronic pain in individuals who have not found relief from other treatments. It delivers electrical impulses to the spinal cord, which interfere with transmitting pain signals to the brain, thus reducing the perception of pain.

Ménière's disease is a disorder of the inner ear characterized by episodes of vertigo (a sensation of spinning or dizziness), hearing loss, tinnitus (ringing in the ears), and a feeling of fullness or pressure in the ear.

Neuropathy refers to a condition that involves damage or dysfunction of the nerves, typically in the peripheral nervous system.

Tinnitus is characterized by the perception of noise or ringing in the ears when no external sound is present. This noise can manifest as ringing, buzzing, hissing, roaring, or other sounds, which vary in pitch and intensity.

Chronic pain is persistent or recurrent pain that lasts for an extended period, typically lasting more than three to six months. Acute pain is a normal sensation that alerts us to possible injury or illness and is usually resolved as the underlying cause is treated. However, chronic pain persists beyond the expected healing time and can become a debilitating condition on its own.

Asthma is a chronic respiratory condition indicated by inflammation and narrowing of the airways, leading to symptoms such as wheezing, shortness of breath, coughing, and chest tightness.

Hypertension, or high blood pressure, is often referred to as the "silent killer" because it typically does not cause noticeable symptoms until it reaches advanced stages.

The prevalence of heart diseases among veterans is a significant concern, as veterans may face unique risk factors related to their military service and experiences.

Sciatica is a condition characterized by pain radiating along the sciatic nerve, which runs down one or both legs from the lower back. The most common cause of sciatica is a herniated or slipped disc, where the soft inner core of the disc leaks out and irritates the adjacent nerve roots.

Diabetes is a chronic condition that occurs when the body cannot produce enough insulin or cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar (glucose) levels.
