Had white count of over 15.5 for 4 years or more. now vomiting every day for 2 months. no energy. hot then cold. low grade fever for a long time.

FUO: Would need more info to comment helpfully. If you have actually had fevers (temps reaching 100f or failing to get as low as 98.6 in 24 hr periods) you have a fever of undetermined origin, and there are dozens or more potential diagnoses, most non-infectious, but the person to see about this would be an infectious diseases expert. This is their bread and butter. Good luck. Try dr. Eugene speck.
