It stared in September of last year. Woke up with stiff neck. When I moved a certain way it would hurt all the down my shoulder then move to my arm. After 6 visits to chiropractor had MRI done. Dealt with pain for about 4 weeks. Got skelatin from dr and a steriod. Help. Now it is mostly my right arm that shakes and my right leg. When I am at a stop sign and have my right foot on brake-it will start to shake. When I'm feeding my daughter and holding the fork or spoon - my arm shakes. Pain if I set too long at my desk too long. Haven't been back to chiropractor since MRI, but did have massage that help with it. I acually had muscle in a knot on my right shoulder when I had the massage.
