Hi. My Sister Has Not Been Right For Some Time

Hi. My sister has not been right for some time for number of years she has had numerous 'boils' in her groin area and upper thighs. Past 2 yrs approx she has been experiencing severe migraines which doctors says are headaches.but when she has them she also has facial drop an right sided weakness which can last from.couple hours to couple weeks. She is experiencing excessive sweating day and night. Could this potentially be leukaemia
She had bloods done this week.her wcc is raised.platelets are slightly low.but gp now sending her for blood film tests?
