I have been having severe neck pain
, numbness and tingling in hands, arms and legs, IBS, bowel discomfort, loss of vision in right eye, black spots in my left eye, sudden sharp pains to my head, trouble concentrating, irritability, and numbness in the right side of my face. My arm went extremely numb one night in bed and I thought I was having a heart attack. Most of my symptoms are only on one side of the body. This has been going on for years and worsened.
