Personalized Pain Care You Can Trust
Serving San Antonio since 1997

At South Texas Pain Institute in San Antonio, Texas, we specialize in helping patients find relief from chronic pain through personalized, comprehensive care. Our practice is led by Shyam Purswani, MD, who is dual board-certified in anesthesiology and pain medicine. Since opening our doors in 1997, we’ve focused exclusively on pain management, treating each patient with compassion and attention.

We take a multimodal approach to pain relief, which means Dr. Purswani looks at your complete picture before recommending treatment. He develops plans based on your condition and what you want to achieve. We have expertise in treating back pain, neck pain, knee pain, elbow pain, car accident injuries, and other chronic conditions. 

Treatment options include an array of cutting-edge and proven techniques, including targeted injections, Multiwave Locked System (MLS) laser therapy, stem cell therapy, physical therapy, and, when needed, minimally invasive procedures like vertebroplasty and kyphoplasty performed right here in the office.

Dr. Purswani completed his medical training at the American University of the Caribbean in Saint Maarten, clinical training at Providence Hospital in Southfield, Michigan, research at Cornell in New York, New York, and residency at Baylor University in Houston, Texas. 

He maintains active board certifications and is a Fellow of Interventional Pain Practice. He regularly lectures on pain management topics to healthcare providers locally, regionally, and nationally.

Our team is committed to managing your pain and empowering you to take an active role in your recovery. When you’ve been injured in an auto accident, we provide detailed documentation for legal cases and work closely with attorneys to support your claim.

Our staff is fluent in Spanish, and Dr. Purswani communicates at an intermediate level in Spanish and beginner level in Russian.
