My husband woke up Thursday morning with stabbing pain in his right shoulder that kind of went up into his neck. He was in a lot of pain throughout the day and went to a chiro. He slept on a heating pad all weekend. He says its a lot better than it was, but the stabbing feeling is still there. I am scared to death its lung cancer. Especially since his biological father passed of this. Will someone please talk me down. That's all that's going through my mind right now.
