Would appreciate your opinions on the possible cause of sudden severe fatigue, loss of appetite, weight loss, dryness in mouth & lips, belching - all occurring 3-4 months after a stem cell transplant for multiple myeloma. Tests are negative - numbers/readings as a result of the transplant are good. These symptoms just started about 2 weeks ago. The only test result we are waiting for is a
thyroid test. My biggest concern is the sudden and extreme fatigue and lack of appetite. I am 65, about 5'5" and 142 lbs. About 9 years ago I was diagnosed with multiple myeloma and given about 6 months to live. Since then, I've managed the disease with chemo and other drugs, and two stem cell transplants.
