I have had increasing pain on the right side of my neck, right shoulder, radiating down my right arm (forearm). It started quite mildly about a month ago, but is now often a constant deep ache. It can be worse at night or when I wake up in the morning, until I actually get up at which point it subsides a bit - then keeps coming and going. Has anyone experienced anything like this? I haven't found that it's related to activity. It can hurt just as much when I'm resting than when I'm using that arm or lifting something. Possibly the reverse correlation is true. Any experiences or advice would be appreicated. Thanks.
