If you have been living with chronic pain for months or even years, you already know that another prescription is rarely the answer. What most people are searching for is a pain management doctor in Portsmouth, NH who will find the source of the problem and treat it directly. That is exactly what interventional pain management is built to do.

At American Pain Institute, Dr. Greenspan offers a full range of non-surgical pain management treatments for patients across Portsmouth and the New Hampshire Seacoast. Below, we break down the most common chronic pain conditions we treat, the interventional procedures that provide lasting relief, and what to expect when you become a patient.

What Is Interventional Pain Management?

Interventional pain management is a specialized approach that targets pain at its source rather than simply masking symptoms. Instead of relying on long-term medication, an interventional pain specialist uses precise, image-guided procedures to calm inflamed nerves, irritated joints, and damaged discs.

The goal is simple: reduce your pain, restore your function, and help you avoid surgery whenever possible. For many patients dealing with chronic back pain, neck pain, and nerve pain, these minimally invasive treatments deliver relief that medication alone never could.

Chronic Pain Conditions We Treat in Portsmouth

Dr. Greenspan has deep experience treating pain throughout the spine, joints, and nervous system. Patients throughout the Seacoast turn to American Pain Institute for help with conditions such as:

  • Chronic back pain, neck pain, and spinal stenosis
  • Sciatica and radiating nerve pain
  • Arthritis, joint pain, and herniated discs
  • Headaches and migraines
  • Fibromyalgia and widespread body pain
  • Nerve damage and neuropathic pain
  • Cancer-related pain
  • Complex regional pain syndrome and neuralgia

If your pain has not responded to physical therapy, medication, or time, an evaluation with a pain management specialist may be the next step toward relief.

Non-Surgical Treatment Options That Target the Source

Most of our patients find meaningful relief without ever needing surgery. Here are the interventional pain management treatments we offer in Portsmouth, NH.

Joint Injections for Arthritis and Joint Pain

When arthritis, bursitis, or worn cartilage makes everyday movement painful, joint injections deliver anti-inflammatory medication directly into the affected knee, hip, shoulder, or other joint. Because the medication goes straight to the source of inflammation, many patients feel relief within days, making it easier to move, exercise, and sleep.

Spinal Injections for Back and Neck Pain

Chronic back pain, neck pain, and sciatica often trace back to inflamed nerves or irritated discs along the spine. Epidural steroid injections and facet joint injections target that inflammation precisely, easing the radiating pain that travels down an arm or leg. For many patients, spinal injections help delay or avoid back surgery entirely.

Radiofrequency Ablation for Long-Lasting Relief

When pain keeps returning to the same nerves, radiofrequency ablation offers a longer-lasting solution. Using gentle heat from radio waves, this procedure quiets the specific nerves sending pain signals to your brain. It is a common and effective choice for ongoing neck pain, lower back pain, and arthritis-related spine pain, with relief that can last many months.

Spinal Cord Stimulator Trials

For severe pain that has not responded to injections, medication, or surgery, a spinal cord stimulator can be life-changing. A small device delivers mild electrical signals that interrupt pain before it reaches the brain. Best of all, you can test the device during a trial period before committing to anything permanent, making it a low-risk way to find real relief.

Regenerative Medicine

Some patients prefer an option that works with the body’s natural ability to heal. Our regenerative medicine treatments support natural repair in damaged joints and tissue, offering a non-surgical alternative for people who want to avoid an operation. You can explore affordable self-pay options on our regenerative medicine page.

Why Patients Choose American Pain Institute

Pain is never one-size-fits-all, so neither is our care. As a private, single-physician practice, American Pain Institute offers something many larger clinics cannot: you see the same trusted doctor every single visit. There is no handing your case from provider to provider and no repeating your story to someone new.

Dr. Greenspan reviews your medical history and imaging before your first appointment, so your visit begins with answers instead of paperwork. From there, he builds a treatment plan around your diagnosis, your goals, and your daily life. You can learn more about each procedure on our pain management services page.

How to Become a Patient

American Pain Institute is a referral-only pain management clinic. Getting started takes two simple steps:

  1. Ask your primary care or treating provider for a referral. We require one for every patient, even if your insurance does not.
  2. Send records related to your pain condition along with any imaging, such as an MRI or X-ray.

Once we review your referral and records, most patients are scheduled within two weeks. Ready to take the first step toward lasting relief? Request an appointment online or call our Portsmouth office at (603) 766-8500.
