My husband who is 51 years old, has been loosing weight, has skin rashes, fatigued a lot, and now is spitting up blood, all in which has been going on for about 3-6 months except the spitting up the blood that started about 2 days ago. These are a few symptoms of my husband, who keeps making excuses for each. I work in a hospital, and have seen it all. I keep telling him that he needs to get checked. I suggested he get an physical. What does my husband's symptoms resemble?
