Step one: find a real doctor. I used to visit a Nurse Practitioner until I realized the next problem he helped me with would be first problem he helped me with.
I can’t think of the name, but there are specialists who look at those blood work numbers like you wouldn’t believe, 10 times more knowledgeable about the numbers, what they mean, and how they interact than a GP doctor.
A blood specialist? Hemotologist?
