There are many reasons a person may experience pain radiating down their arm. This pain can include numbness, tingling and burning if the cause is from nerve compression. It could be caused from cervical bulging/herniated discs, stenosis, adhered nerve roots and thoracic outlet syndrome just to name a few. One factor that is commonly overlooked that can can play a major role is the mobility of the first rib. In the picture below, if the first rib is too elevated, the brachial plexus can be compressed. 

At Mana Physical Therapy, we are specially trained at assessing and mobilizing joints, including this first rib. If this first rib is limited with depression range of motion, we will perform joint mobilization techniques to restore normal range of motion which will result in reduced symptoms of pain down the arm.
