Several month ago I got an arm numbness syndrome. I tried everything that I could find, including exercises, lotions, etc., and nothing worked. So, I decided to try Nervous System Vitaal from Sensipharm. I should say I was already familiar with Sensipharm, as I used it for my dog health problems and it worked very well! After two months the numbness has completely gone! After several months of suffering, it was a real relief. I am very satisfied with this treatment and would certainly recommend it!
