To say your medical mystery, is complicated, is an understatement! I’m sure you leave a number of doctors scratching their heads as they try to put all the clues together for a complete picture of your puzzle! From my own experience, I’ve learned just how complex blood cancers can be. There are cellular subtleties, variations in mutations, other co-morbidities that can split a diagnosis off into different directions.

CLL and Lymphoma are both blood related cancers. Leukemia originates in the bone marrow and spreads through the blood, while lymphoma originates in the spleen or lymph nodes and spreads through the lymph vessels. It is possible to have both. So further testing may have shown lymph node involvement adding lymphoma to the original CLL. They can share similar symptoms, too. And so can sarcoidosis with fatigue, fever, night sweats, bone and muscle pain, swollen lymph nodes.
Actually a friend of ours had pulmonary sarcoidosis with many of those symptoms when he was in his early 40s.
Once diagnosed he was given steroids for several months and back to normal. That was 30+ years ago and he’s a healthy, active old codger now…so am I so I can make that joke. ☺️

So hang in there. You have doctors who are taking this seriously and getting you the testing that’s necessary. The wheels can feel like they’re turning slowly but testing can be progressive as each one may rule something out or guide the doctor to another area.
It’s awful to feel so miserable so I really hope you get some answers soon. Are there any pain meds suggested to help keep you comfortable while you wait?
