Welcome to Texas Pain Consultant Associates

Pain is familiar to all of us and is probably the most common reason someone sees a doctor. Pain at times indicates injury and is obvious with a broken bone or a cut, but other times can be more mysterious and may represent a symptom like infection or inflammation.

When pain is thought of as a symptom it can come from a broad variety of sources and vary widely in its presentation. If you don’t know the cause of your pain, answering that question should be the first step. The physicians of Texas Pain Consultant Associates can help to identify the cause of your pain, so that the most effective treatment can begin. We work with your doctor to help evaluate, diagnose and treat a variety of pain problems.

The first step to recovery is, of course, the evaluation, so don’t hesitate, take a step!
