My poppy (his name is Chester) hasn't been feeling well for the past few months. He has chest pain, back pain, loses his breath, is very tired and weak, has numbness in his left arm/hand occasionally, also sometimes he throws up after eating certain meals and mostly recently he has had diarrhea. Doctors ran blood tests, stress tests and ruled out any complications with his heart. They now plan to check his lungs. He is only 63 years old and I love him very much. He has been my father figure for years.. bought me my first car and prom dress.. I worry about him a lot and fear that the doctors won't be able to find what is wrong. I just want him to get better and be back to his normal self. I don't want him in pain anymore. I am just wondering if anyone here may be able to identify what is wrong or what we should get checked out.. any insight would be very much appreciated. God bless you all.
