• Headaches
• Arthritis
• Fibromyalgia
  From old sports injuries to cancer, chronic pain management is something many people need. The goal is the same: eliminate as much pain as possible, improve your mobility, and improve your quality of life. Unfortunately, chronic pain can continue even after the injury or illness that initially caused the pain is resolved. Pain signals remain active in the nervous system for weeks, months, or years. Some people can experience suffer chronic pain even when there is no past injury or apparent body damage. Chronic pain is linked to conditions including headaches and migraines, arthritis, cancer, nerve pain and diabetic nerve conditions, back pain and back injuries, and fibromyalgia.

Radiologist

• Ultrasound
  An echocardiogram, also known as an echo test or heart ultrasound, is a test that takes pictures of the heart using sound waves in order to evaluate the structure and function of the organ. Unlike X-rays and other forms of cardiac testing, echocardiograms do not involve any radiation. There are several types of echocardiography tests, however, the most common test is the transthoracic echocardiogram (TTE). A stress echocardiogram is another type of test, which can identify heart problems that only occur during physical activity.

Even if it spreads into nearby lymph nodes, surgical treatment followed by chemotherapy is usually highly effective.

Surgeons

• Joint Replacement
  Hyaluronic acid injections involve the application of hyaluronic acid, which is a substance naturally found in the synovial fluid of joints. Injecting synthetic hyaluronic acid into a joint can cushion and lubricate the joint, thus improving movement and reducing pain. Hyaluronic acid injections are beneficial for the treatment of osteoarthritis of the knee. This treatment option may also be a good procedure for a patient who has a health condition that makes him or her a poor candidate for a joint replacement, or for those patients who have to wait to undergo a joint replacement surgery.
