Double crush syndrome means a nerve is compressed at more than one location along its course. The idea is that having a proximal compression (such as at the cervical spine) can make the nerve more susceptible to symptoms from a distal compression (like at the carpal tunnel), so patients may have symptoms from two sites contributing to the overall picture. Because the problem involves multiple entrapments, simply treating one site may not fully relieve symptoms unless both areas are considered and addressed. It’s not limited to the upper limb; any nerve along its path can be affected at multiple points. Symptoms typically include paresthesias and pain in the nerve’s distribution, and aren’t confined to nighttime only. The statement describing a single entrapment site doesn’t fit this pattern, since double crush implies more than one compression along the nerve.
