Are you suffering from numbness or tingling in your arm or fingers? It could be TOS.



"Thoracic outlet syndrome (TOS), a group of diverse disorders, is a collection of symptoms in the shoulder and upper extremity area that results in pain, numbness, and tingling."


Yoon Clinic provides Acu-NETTP Injection therapy, which allows a significant improvement in the symptoms of TOS.


In practice, brachial plexus nerve entrapment of the inter-scalene (the space between anterior and middle scalene) is the most common cause of TOS. It is because of the heavy use of computers and cell phones. The forward pull of the weight of the head and elevated shoulders puts undue stress on the neck muscles such as scalenes. The chronic tension in the scalenes will constantly irritate the nerve, which will induce numbness and tinglings in the arm.


Dr. Yoon performs Acu-NETTP Injection with an ultrasound guide, which helps to achieve safe and precise injection into the targeted muscles (scalene muscles). The injected muscles will release its tensions, and the overstimulated nerve issue also will be resolved. Many of our patients do see significant improvement within two weeks with course 3~4 treatments.
