Comprehensive Spine Care in San Antonio
Many patients in San Antonio seek evaluation for persistent back pain, neck pain, numbness, tingling, or leg weakness. Our goal is to determine whether symptoms are caused by disc herniation, spinal stenosis, degenerative disc disease, sacroiliac joint dysfunction, or spinal instability — and recommend appropriate treatment options.

Advanced & Minimally Invasive Spine Treatments
New innovative treatment option for patients suffering from radical pain due to cervical disc degeneration.
Both cervical fusion and Mobi-C Cervical Disc replace the damaged disc(s) and try to match the healthy disc height, removing pressure on the nerves. Fusion surgery typically requires an anterior metal plate to keep the interbody spacer in place and to stop movement at the surgical level(s).
In contrast, Mobi-C fits entirely within the disc space and is designed to maintain neck movement, which may help reduce adjacent levels from degenerating.
Spine & Back Conditions We Treat in San Antonio
At MD Spine Care, we evaluate and treat a wide range of spine conditions affecting the neck, mid-back, and lower back. Whether symptoms are caused by nerve compression, disc degeneration, spinal arthritis, or trauma, identifying the underlying condition is essential for effective treatment.
Cervical Pain (Neck Pain)
Neck pain, also known as cervical pain, can develop from disc herniation, arthritis, spinal stenosis, muscle strain, or nerve compression in the cervical spine. Symptoms may include stiffness, headaches, shoulder pain, or radiating pain, numbness, or tingling into the arms. Persistent cervical pain that lasts more than several weeks should be evaluated to determine whether the cause is muscular or related to structural spine changes. At MD Spine Care in San Antonio, we assess the underlying source of neck pain and recommend conservative treatment options whenever appropriate before considering surgery.
Lumbar Pain (Lower Back Pain)
Lower back pain, or lumbar pain, is one of the most common reasons patients seek evaluation. It may result from degenerative disc disease, herniated discs, spinal instability, arthritis, or sacroiliac joint dysfunction. Symptoms can range from localized aching to sharp pain that worsens with movement. Identifying whether the pain is mechanical, inflammatory, or nerve-related is critical for determining the right treatment approach. Patients in San Antonio experiencing persistent lower back pain may benefit from imaging and a comprehensive spine evaluation.
Cervical & Lumbar Herniated Disc
A herniated disc occurs when the inner portion of a spinal disc pushes through its outer layer and irritates nearby nerves. In the cervical spine, this may cause neck pain and arm symptoms. In the lumbar spine, it may cause lower back pain and sciatica. Symptoms often include radiating pain, numbness, tingling, or weakness. Many herniated discs improve with conservative care, including physical therapy and medication. However, persistent or worsening neurological symptoms may require further evaluation to determine whether surgical treatment is necessary.
Sciatica
Sciatica refers to nerve-related pain that travels from the lower back into the buttock and down the leg. It is typically caused by compression of the sciatic nerve due to a herniated disc, spinal stenosis, or degenerative changes in the lumbar spine. Symptoms may include sharp leg pain, burning sensations, numbness, or weakness. While many cases improve with conservative treatment, prolonged or progressive symptoms should be evaluated by a spine specialist in San Antonio to prevent long-term nerve damage.
Spinal Stenosis
Spinal stenosis is a narrowing of the spinal canal that places pressure on the spinal cord or nerve roots. In the lumbar spine, this often causes leg pain, numbness, or difficulty walking that improves when sitting. In the cervical spine, it may cause balance issues or hand weakness. Spinal stenosis typically develops gradually due to age-related degenerative changes. Treatment may include physical therapy, injections, or surgical decompression depending on severity and symptom progression.
Spinal Fractures
Spinal fractures may occur due to trauma, falls, motor vehicle accidents, or weakened bones from osteoporosis. Symptoms can include sudden back pain, limited mobility, and tenderness over the affected area. Some fractures are stable and may heal with bracing and conservative care, while others may require surgical stabilization. Early diagnosis is important to prevent further instability or nerve compression. Patients in San Antonio who experience back pain after trauma should seek evaluation promptly.
Traumatic & Auto Accident Spine Injuries
Motor vehicle accidents and traumatic injuries can cause disc injuries, ligament damage, spinal instability, or fractures. Even when initial imaging appears normal, persistent back or neck pain following an accident should not be ignored. Symptoms may develop gradually as inflammation increases. A thorough spine evaluation can determine whether structural injury or nerve compression is present and guide appropriate treatment to prevent chronic pain.
Sacroiliac (SI) Joint Dysfunction
Sacroiliac joint dysfunction occurs when the joint connecting the spine to the pelvis becomes inflamed or unstable. SI joint pain is often felt in the lower back or buttock and may mimic sciatica. Pain typically worsens with prolonged standing, walking, or transitioning from sitting to standing. Accurate diagnosis is essential because SI joint pain can be mistaken for lumbar disc problems. Treatment may include physical therapy, injections, or minimally invasive stabilization procedures when conservative measures fail.
If you are experiencing persistent back or neck pain, radiating symptoms, numbness, or weakness, scheduling a spine evaluation in San Antonio can help determine the underlying cause and appropriate treatment plan.
