MRI found asymmetric swelling of the right brachial plexus at the level of scalene muscle region.  They have increased signal intensity.  The fibre of right brachial plexuses are not well-defined.   Please clarify and advise if the tingling/numbness on my right arm is caused by brachial plexuses or scalene muscles?  If mild fascia release treatment can be used and where to find a therapist who can do this  in Hong Kong?
