Husband is over 68. Has several symptoms times several months. Most troublesome is unintentional weight loss. Probably lost 50 lbs or more. Has weakness and shaking in hands. Has nausea and some vomitting. Has runny nose. (not so much it's a huge problem). Also suffers from depression. Also has a hernia in groin that protrudes into testicles and is sometimes very painful- other times better. Never been to a doctor in his life. Not sure I could get him to go.
