Hello, I have a herniated disc at C3 and was told years ago that it was pinching on a nerve that is causing my right arm to have pain, and my middle, ring, and pinky fingers on my right hand to get numb and tingle. I had bilateral carpule tunnel, had surgery on the right hand, and was fine until this accident in the grocer when I was hit in the back with a milk crate full of milk that fell off a pallet of crates. Lately my left arm has been hurting so bad in the triceps, now in the forearm, Is this also related or is this something new going on??
