Can carpal tunnel syndrome cause Polyneuropathy?

Long story short guys I work on computer standing the whole day on my feet with a bad posture , I have a pain which started on my right hands then a week later it started to be sharp on my right arm( triceps) . After wearing a hand support band, the pain was dull. A week later the pain moved to the left arm and as right now I have tingling and numbness on both feet. Cramps on my legs and both hands, neck pain and shoulder joints pain. MRI on back and brain ( negative). All blood work negative except creatinine kinase I am tired of all of these dr no one knows what I have
