Understanding Pain

Horizon Spine and Pain Specialists focuses on two types of pain: new and long-term.

Acute pain management is designed for active adults who have new pain symptoms and need the help of a specialist. In some cases, pain control is not just a matter of comfort but is also a matter of medical safety that can contribute to the healing process.

Chronic pain is a complex condition that refers to pain lasting longer than expected for a disease or injury. It is frequently severe enough to limit a person’s activity and make it difficult to function at work or at home.

Let us find treatment solutions that help you get back to what matters.
