Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Are there any hematologist/rheumatologist crossover doctors? Like a single doctor who specializes in autoimmune hematology? It feels like rheumatology and hematology pass me back and forth and like both of them think I'm the other specialist's problem.. ### Response: Not that Im aware of unfortunately. The problem is they are both at dead ends and think the other specialty will be able to help. Which is why you need your case elevated to the next level.
