Do you think i have leukemia? it started with a sore throat, rashes, bruising, itchy skin, muscle pain, nerve pain? it's improving. had no fever.

No: You have a better chance of winning powerball.

Leukemia: Nope. That would be so far down the list of probabilities that i wouldn't even worry my patient with that unlikely possibility. Why do you ask? Why would you worry about something so rare when there are so many other explanations for your symptoms?

Unlikely: These symptoms can be interpreted many ways, but if leukemia were present (which is very improbable) the symptoms would not improve, but get progressively worse. Sounds as if you have been reading texts looking for a diagnosis and are learning that there is more to medical practice than is written down. See a good clinician. Good luck and get better soon.
