My mother is 47 and she has fibromyalgia. A couple weeks ago, her arm started to hurt. The pain starts at the right side of her neck. It goes down her shoulder, and follows her muscles and tendons all the way down to her wrist. Her lymph nodes are swollen and her muscles are very tight. Her chiropractor told her that she has pinched nerves on her neck, and that she needs to massage, ice, and stretch it. She s been doing this, but the pain has only been getting worse. Any idea what it might be?
