Hi,
I was checked for JAK2 by a rheumatologist looking to see if I had rheumatoid arthritis. I have no JAK2 mutation and do not have rheumatoid arthritis but do have one enlarged right finger proximal interphanageal joint huge enlargement with no pain and an enlarged right sternoclavicular joint also with no pain. My high platelets were found on routine blood work 12/11/24 but have decreased by 411 doing nothing differently and no meds. These rare blood cancer diagnoses are very confusing, but at least good as slow progression if we have them.
