One of the options for pain relief that you may or may not have considered is chiropractic. Many people overlook the benefits and the role that chiropractors provide. Yet chiropractors offer millions of people around the world with a non-invasive pain relief and treatment approach that has helped so many.

As a drug-free and non-invasive treatment option, you should consider the chiropractor’s office as the first stop in your journey towards wellness and health. An experienced and trained chiropractor such as Dr. Amin Nia at Spectrum Medical can help you with:

  • Back pain
  • Neck pain
  • Lumbar and disc issues
  • Tissue pain such as tendons, muscles, and ligaments
  • Headaches
  • Many, many more…

When caught and treated early by your chiropractor, long-lasting and degenerative changes can be prevented, allowing you to enjoy many more years of good health.

The most significant aspect of any chiropractic treatment is chiropractic manipulation of the spine or joints of the extremities. Commonly referred to as an “adjustment”, chiropractic manipulation is performed to improve lost range of motion, increase segmental joint mobility, stimulate joint position sensors and promote normal function of the central nervous system. The adjustment is vital in restoring normal joint function and range of motion and improving overall joint health.

Chiropractic manipulation is a safe, gentle and effective method for treating neck, mid back and lower back pain in addition to disorders of the shoulder, elbow, wrist, hip, knee and ankle. By restoring normal function to the musculoskeletal system, especially the joints of the spine, manipulation allows the nervous system to operate without interference and regulate the various systems of the body and promote optimal health.

What is PRP Therapy?

Platelet-Rich Plasma (PRP) Therapy is a conservative and holistic approach to increase the healing speed of damaged tissues. PRP uses super concentrated platelets and is commonly done to complement other procedures or on specific localized chronic pain issues.

How is PRP therapy administered?

A qualified professional will draw a small amount of blood and spin it in a centrifuge, isolating the platelets. The site of injury is then treated using the PRP preparation. PRP is carefully injected into the injured area combined with local anesthesia. This will trigger the body’s natural healing process, basically initiating the immune response.

It is expected to experience pain for the first two weeks after the procedure, however pain is reported from mild to minimal.
Benefits of PRP Therapy

 PRP Therapy may be used to improve healing after surgery for some injuries. The ultimate goal of PRP is to eliminate pain through healing while providing results that last. Research studies have shown that PRP therapy can be effective in relieving pain and helping patients return to their normal lives.


Who May Benefit from PRP Therapy?

 PRP is often used as therapy in the following conditions and may help improve the following:

  • Pain due to joint arthritis of the shoulder, hip, thumb or knee
  • Chronic tendonitis in the elbow, hip, knee, foot and ankle
  • Tendon injuries
  • Ligament sprains
  • Sports related muscle tears
  • Carpal tunnel syndrome
  • Facet joint injuries inducing spinal pain
  • Sciatica caused by a herniated disc or spinal stenosis
  • Fractures

Say Goodbye to Knee-Pain, Without Surgery

Over 85% of Successful treatment

Hello, I am Dr. Arlen Green. Did you know that more than 100 million Americans suffer from knee pain? Have you asked yourself how different would it be if you could get rid of that pain? You don’t need to wait any more to have the most advanced treatment, without surgery, approved by the FDA. Recover your life now

Have you considered surgery?

People who suffer from knee pain take supplements or pain killers before seeking advice from a doctor. When the pain continues, many think that surgery is the only option. Before you face this situation and have to pay un-necessary bills, consider another option.

What is available to treat knee pain?

After a careful study and several tests, the FDA approved a new treatment aimed to people with knee pain. This new treatment is a high technology answer to those who think that surgery, diet supplements, and prescribed medicine are an option to eliminate the pain.

How does the treatment works?

The ultrasound technology allows doctors to identify the problem area, with great accuracy. A viscosupplement injection is given. This injection is a natural component that lubricates joints, reduces pain and infl ammation. This procedure is as easy as given a vaccine shot.

When will I feel the changes?

Most of the people experience improvement within weeks and can start enjoying their everyday activities

Common causes of knee pain:

  • Arthritis of the knee – Arthritis most often causes problems with the knee joint, but also can affect other structures such as muscles, tendons, and ligaments. Osteoarthritis, the most common form of arthritis in the knee, is caused by the gradual degradation of the cartilage in the joint. Rheumatoid arthritis causes the joint to become inflamed and can often cause destruction of the surrounding cartilage. A deformity often leads to arthritis in the knee, but more often, obesity or excess weight, or repetitive stress injuries from sports, are the culprit. Symptoms include stiffness or locking joints.
  • Cartilage injuries – including chondromalacia patella, a softening of the knee cap cartilage. This disorder occurs most often in runners, skiers, cyclists, and soccer players.
  • Iliotibial band syndrome – Inflammation of a tendon and its subsequent rubbing over the outer knee bone is most often caused by the stress of long-term overuse, such as sports training. Symptoms of iliotibial band syndrome include aches or burning sensations at the side of the knee; sometimes, the pain can radiate up the side of the thigh.
  • Ligament injuries – The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) can become sprained, and cause a great deal of pain. Injury to the cruciate ligaments is sometimes referred to as a “sprain.” The ACL can become stretched or torn by a sudden twisting motion. The PCL is most often injured by a direct impact, such as in an automobile accident or football tackle. Injuries to the medial collateral ligaments are often caused by a blow to the outer side of the knee that stretches and tears the ligament on the inner side of the knee. Football and hockey players often incur these kinds of injuries. The injury is often accompanied by a “pop” sound, followed by a buckling of the knee sideways.
  • Meniscus injuries – Quick twists or rotations of the upper leg or repetitive rotations of the knee while bearing weight can tear the meniscus.
  • Osgood-Schlatter disease – This condition is caused by repetitive stress or tension on the upper tibia, or leg bone. The patellar tendon and surrounding soft tissues at the point where the tendon attaches to the tibia can become inflamed. Pre-adolescent boys involved in sports that include frequent running or jumping are particularly prone to this condition.
  • Tendon injuries – Tendon injuries in the knee can be caused by anything from tendonitis to a ruptured or torn tendon. Overuse can cause the tendon to stretch like a rubber band, later becoming inflamed.
