Welcome to American Pain Institute! At American Pain Institute in Portsmouth, New Hampshire, every patient is heard. Whether you are suffering from chronic back pain or a recent injury, you will be treated with dignity and respect throughout the process of assessment, diagnosis, and treatment. American Pain Institute will provide you with the quality and accessible pain management care you deserve.

Our State-of-the-Art facility in Portsmouth NH was built with our patients' comfort in mind.

Stem cell therapy has been proven to be an effective treatment for chronic joint pain, and most muscle, tendon, cartilage, and nerve problems. During this non-surgical procedure, stem cells are injected into the problem area of the body. These stem cells encourage and speed up the body’s natural healing process, regenerating tissue in the injured area.

The stem cells that we use at Main Street Wellness & Regenerative Medicine are from a donor bank that is accredited with the American Association of Tissue Banks. Known as MSCs or Mesenchymal stem cells and numerous building blocks such as growth factors, collagens and anti-inflammatories called the Matrix, these are collected from umbilical cord gel. All of our stem cells are tested for viability and cryopreserved.

Patients seeking relief from joint and tendon pain can consider a state-of-the-art procedure called platelet-rich plasma (PRP) injections. The team at New Hampshire Regenerative Center LLC in Manchester, New Hampshire, offer this safe therapy as an alternative to cortisone injections, anti-inflammatory medications, and surgery. PRP Injections are effective in reducing pain and inflammation in the joints and tendons, with no unpleasant side effects. Find out if PRP injections are the option for you by calling or scheduling an appointment online.
