wcb did give me a tens machine for pain plus they are talking about some nerve block pump what ever that is , every time i see a wcb doctor they are amazed by how blue my arm goes and if i use it for and time i lose my pulse completly , tos sucks but losing myself is worse so much has been lost and now depression plus pain and turn blue is my normal life good thing i decided when i had kids i got rid of my guns because i prob would have hurt myself .
