Hi.  Im experiencing numbness and swelling in my hands and feet.  But much worse in my hands.   The left seems worse..   This is throughout the day periodically ..but mainly at night.   I awake at night and feel as if I couldntmake a fist.   Is this something serious?
Hello, You have not mentioned your age which is important in judging the list of possible causes. For example, after age 40 cervical spondyloses gets commoner and one of the signs of cervical spine spondylosis is numbness and swelling of hands and feet. Also, an underactive thyroid can make this worse. It is important that you see a Neurologist (Medicine not Neurosurgery) to begin with and get an opinion. Best Wishes.
