I am a new newbie ... I just got my approral today for the Nervo Senza trial. I have to do a training day that will cost me €600 .. it is very expensive for what it is, but there is no choice with this! It is compulsory. I am wondering does the nervo senza cover upper and lower body pain? Also if you turn if off for example say to go on a plane for four hours, does it take 12 to 24 hours to kick in and give you relief again. Can anyone answer my questions. Are you happy with the nervo senza and what are the disadvantages? Hope you are having pain free days. gentle Hugs, Pauliana
