I had C4, C5 and C6 spinal fusion last July, and now I have noticed about an inch difference in size of arms. My right shoulder, arm, hand and chest continue to get electrical, burning and sharp pain, especially when I type for more than 5 minutes. My right arm is now about 1/2 to 1 inch smaller than my left side, and my shoulder is now hurting all the time. I have complained about the medication
